Description

The invention relates to laser systems of teleorientation (LST) and can be used to control moving objects with teleorientation in the laser beam.

At present, guidance systems using the principle of teleorienting a controlled object in a laser information field are widely known - a raster whose information axis passing through the center of the laser raster is aligned with the line of sight of the target (U.S. Patent 4111383, NKI 244 - 3.13, 09.09.78). The main problem that arises in such systems is the problem of noise immunity, which includes the noise immunity of the optical communication line and the issues of stealth.

The noise immunity of the optical lines of communication “sighting channel of the guidance system - target” and “laser guidance channel - receiver of a controlled object” in such systems is significantly reduced due to the accumulation of smoke from the object’s engine or the formation of a dust cloud when it is launched on the target’s line of sight, which with small side winds lead to both loss of visibility of the target by the operator and disruption of control of the object with insufficient energy potential of the used LST.

The secrecy of similar systems at the current level of development and equipping of technology with laser radiation detectors practically disappears and the application of a laser guidance beam on the target during the entire guidance time gives a lot of time to counter (smoke interference for the control channel, laser counteraction for the target channel, etc. .).

An increase in the noise immunity of the LFB is achieved by the fact that for systems having a position-controlled launcher, the laser beam is formed so that the optical axis of the beam is shifted before the launch of the object, for example, it is raised for ground launchers by a certain amount relative to the line of sight of the target. The magnitude of the displacement remains constant as the object flies, and only when approaching the target at a given range, according to a certain law, this displacement is reduced to zero, that is, the optical axis of the beam is combined with the line of sight of the target. For systems with a rigidly fixed launcher, the object is launched without bias, and then, according to a certain law, the optical axis of the beam is raised relative to the line of sight of the target, and when approaching the target at a given range, this bias is reduced to zero by a certain law.

In this case, the laser beam irradiates the target for a short time when it is superimposed on the target.

To exceed the optical axis of the beam over the line of sight of the target in the LST design, a controlled optical element is used — a plane-parallel plate made with the possibility of rotation about an axis perpendicular to the axis of the guidance channel and installed in front of the output optical system with a variable focal length (RF Patent 2183808, MKI F 41 G 7/26, 12/21/1999). Increasing the noise immunity of the guidance system with the proposed sight is carried out by rotating the plane-parallel plate by a certain angle, which leads to an angular deviation of the optical axis of the guidance beam relative to the line of sight of the target. The displacement of the beam and the flight path of the controlled object frees the line of sight of the target from engine smoke and significantly reduces the possibility of detecting laser radiation by the target. The software device allows you to implement a set of laws for entering and removing excess, that is, to start the entire mechanism for introducing excess at the right time and using the data on the range to the target received from the rangefinder channel, determine the moment when the excess is removed and the object is brought to the line of sight immediately before it approaches the target.

The disadvantages of this LCF include the following. The introduction of a rotatable plane-parallel plate, its position sensors, and control drives increases the weight and dimensions of the laser teleorientation system. The use of mechanical plate control drives and changing the equivalent focus of the forming optical system requires additional time to return the drives to their original position. In addition, LCFs containing mechanical drives for scanning or spatial modulation of the laser beam and changing the equivalent focus of the forming optical system have significantly lower energy potential due to the restrictions imposed on the type of laser used and due to the decrease in the density of laser energy in the information field due to the need the formation of a laser beam of a large area. It is also obvious that the introduction of a rotating plane-parallel plate provides an angular deviation of the optical axis of the control beam relative to the line of sight of the target in only one vertical direction, which is acceptable only for ground-based control systems.

When placing the BLF on an air carrier, airplane or helicopter, it is advisable to have an angular deviation of the optical axis of the control beam relative to the line of sight of the target in the horizontal direction. In the general case, a universal LCF should be able to choose the direction of the angular displacement of the optical axis of the laser control beam relative to the line of sight of the target, as well as the ability to choose the optimal law for the type of controlled object to reduce this displacement to zero.

There are known LFWs with great energy potential and wide opportunities for modernization, selected as prototypes and including a laser in series, an optoelectronic scanning system and an output optical system, as well as an electronic control unit in which the formation of a laser raster is carried out by scanning a laser beam with "needle-shaped" radiation pattern by an acousto-optic deflector.

In LST (patent RU No. 2093849, priority 13.12.95), (V. M. Semenkov, O. T. Chizhevsky. Prospects for the creation of multi-channel LST managed objects. Scientific and technical collection "Ammunition and Special Chemicals", ser. "Ammunition", M., TsNIIMTIK PK, 1995, v.5-6, p.26-30) the optoelectronic scanning system contains two crossed acousto-optic cells, which are controlled by the supply of high-frequency signals that are tunable in frequency. The deflection angle of the laser beam at the output of each cell is proportional to the frequency of the high-frequency signal supplied to the cell. The formation of high-frequency control signals is carried out in an electronic control unit containing a series-connected block for the generation of clock signals and raster parameters, a raster code generator and a two-channel code-frequency converter. The raster code generator produces binary codes that, after converting them to high-frequency signals, determine the position of the laser beam in space. The law of change of these codes determines the path of scanning the laser beam in space — horizontal or vertical lines of the laser raster and the type of raster — command or information. The control signals establish the number of lines and the angular dimensions of the laser raster in space.

LST with an increased range of operating ranges (patent RU No. 2177208, priority 19.11.1996 (No. 2093848, priority 28.11.95) IPC: N 04 V 10/10) includes a laser, an optical-electronic scanning system and an output optical system, and also an electronic control unit. The optoelectronic scanning system in it consists of two crossed anisotropic acousto-optic cells and a third acousto-optic cell, installed similarly to the second, and a two-channel switch of a high-frequency signal, and the output optical system contains two telescopes of the optical channels of the “near” and “far” control zones. In such a LST, the alternate connection of identical acousto-optical cells located before and after the polarizing prism to the electronic control unit made it possible to independently form laser rasters of the “near” and “far” control zones.

These BLFs have high energy potential.

The objective of the invention is to increase the noise immunity of the LST and increase the methods of controlling the object.

To achieve the specified technical result in the known laser teleorientation system, including a laser, an optical-electronic scanning system, an output optical system and a deflector control unit, comprising a series-connected unit for generating clock signals and parameters of a raster generated by scanning a laser beam, and a raster code generator, as well as two-channel frequency synthesizer, an adder and a shaper of displacement codes are introduced into the deflector control unit so that the raster codes z _t and y _t from the output of the raster code generator and the offset code Kφ from the output of the generator of the offset codes are fed to the inputs of the adder, which provides its outputs connected to the inputs of the two-channel frequency synthesizer, the formation of codes z _с = z _т , у _с = у _т + Kφ, or z _c = z _t + Kφ, y _c = y _t , or z _c = z + Kφ _t , y _c = y _t + Kφ, and the control inputs of the shift code generator are connected to the control outputs of the clock generation unit and the raster and shaper parameters raster codes, and the system is configured to enter the "Descent" command "to the input of the block for generating clock signals and raster parameters.

The displacement code generator is made in the form, for example, of a serially connected timer of temporary states, a calculator of the normalized alignment curve, configured to provide the law of change of the alignment curve, in the form, 1st ^{-t / τ} , where τ is a constant that determines the rate of decrease, t - the current time from the beginning of the reduction, the multiplier, the subtracting device and the register, as well as the calculator of the constant bias codes, the trigger and the logic circuit "I", while the output of the calculator of the constant bias codes is connected to the inputs of the mind life and subtraction device, the second output of the timer of temporary states is connected to the input of the setting "0" of the trigger, the output of which is connected through the logic circuit "AND" to the inputs of the calculator of constant bias codes, the calculator of the normalized alignment curve and the timer of temporary states, while the second input of the circuit " And "connected to the control output of the block for generating clock signals and raster parameters, the control input of the register is connected to the control output of the raster code generator, and the input of the" Range "timer is temporary conditions connected to the external bus input range to the target, wherein the system is adapted to enter the command "Ret" to set input "1" trigger.

Shaper raster ECU codes generates binary codes z _t and y _t, which are, if not consider the influence of the newly introduced shaper offset codes, and the adder converted two-channel synthesizer frequency tunable time-frequency signals f _z and f _at supplied to the optoelectronic scanning system . The law of change of these codes determines the trajectory of scanning the laser beam in space — horizontal or vertical lines of the raster and the type of raster — command or information. Using control signals, it also sets the number of lines and angular dimensions of the raster in space. The control signals to the raster code generator are issued by the block for generating clock signals and raster parameters, controlled by external commands. After the external “Start” command has been issued, the laser is turned on, and after the external “Bypass” command has been issued, the raster parameter clock generation unit is turned on, which generates, at the required time interval Δt _{i, the} angular size codes of the raster M _K , the end-of-frame gate E _K , and also the switching signal range U _l for LST with increased range.

A laser beam passing through an optoelectronic scanning system deviates along two coordinates, forming a raster in space, the linear dimensions of which in the plane of the controlled object correspond to the calculated values. The angle of deviation of the laser beam at the output of the optoelectronic scanning system is proportional to the frequency of the supplied high-frequency signal.

In LST with an increased range of operating ranges, the formation of control signals is also carried out in the electronic control unit, however, scanning is performed by an optical-electronic scanning system consisting of two crossed anisotropic acousto-optic cells and a third acousto-optic cell, installed similarly to the second, and a two-channel high-frequency signal switch, as well as output optical system consisting of two telescopes. This LST allows you to create a laser raster first in the optical channel of the "near" zone, and then in the optical channel of the "far" control zone. Channel switching is carried out by a two-channel switch of a high-frequency signal, controlled by a range switching signal U _l , by connecting acousto-optic cells located after and before the polarizing prism to the outputs of a two-channel frequency synthesizer.

An increase in the noise immunity of the LST and an increase in the methods of controlling an object using a laser raster are achieved in that the laser raster is formed so that the center of the laser raster is shifted relative to the line of sight of the target by a certain amount. The magnitude of this displacement remains constant as the object flies, and only when approaching the target at a given range, according to a certain law, the center of the laser raster is combined with the line of sight of the target.

To ensure such a bias, a bias code generator and an adder are introduced into the LST, which generate and supply bias signals to a two-channel frequency synthesizer. The offset code generator allows you to implement a set of offset and input offset laws, using the data on the range to the target obtained from the rangefinder channel, determine the start of offset offset and then combine the center of the laser control raster with the target line of sight.

Thus shaper offset codes produced displacements codes Kφ, varying in time depending on the distance to the target, which, together with the codes z and _{r t,} codes are generated by a raster generator are supplied to an adder. The adder is designed in such a way that at its outputs connected to the inputs of the two-channel frequency synthesizer, codes z _c = z _t , y _c = y _t + Kφ (if LST is located on the ground launcher), or z _c = z _t + Kφ , y _c = y _t , or in the general case z _c = z _t + Kφ, y _c = y _t + Kφ (if the LST is placed on an air carrier). These codes are converted by a two-channel frequency synthesizer into time-tunable high-frequency signals fz _c and fy _c supplied to the optoelectronic scanning system, determining the shift of the center of the laser raster relative to the line of sight of the target.

Two crossed anisotropic AOA 4.1 and 4.2 placed s between the laser and the polarizing prism 4.4. The control input AOI 4.1 is connected to the first output of the DSL 9. The AOA 4.3 is installed similarly to the second AOA 4.2 and is located between the first output of the polarization prism 4.4 and the telescope of the “near” zone 5.1 of the BOC 5. An optical reflector 4.5 is located between the polarization prism 4.4 and the telescope of the “far” zone 5.2 OSI 5. The outputs of the DCHF 4.6 are connected to the AOA 4.2 and 4.3. The high-frequency input DKHChS 4.6 is connected to the second output of the MFD 9, and the control input is connected to the output of the switching range BFSiPR 6. The inputs of the adder 8 are connected to the outputs FKR 7 and the output of FKS 10, and the outputs to the inputs of the MF 9. 9. The control inputs FKS 10 are connected to control outputs and BFSiPR 6 and FKR 7, as well as with an external input bus for range to the target, while it is possible to enter the “Descent” command to the input of BFSiPR 6.

FCC 10 consists (Fig. 3) of successively connected timer of temporary states 10.1, calculator of normalized alignment curve 10.2, multiplier 10.3, subtractor 10.4, register 10.5, as well as calculator of constant offset codes 10.6, trigger 10.7, logic circuit "And" 10.8. The output of the constant offset code calculator 10.6 is connected to the inputs of the multiplier 10.3 and the subtractor 10.4. The second output of the timer of temporary states 10.1 is connected to the input "Set 0" of trigger 10.7, the output of which through the logic circuit "And" 10.8 is connected to the inputs of the timer of temporary states 10.1, the calculator of the normalized alignment curve 10.2 and the calculator of constant offset codes 10.6. The second input of the logic circuit "And" 17.8 is connected to the control output of the BFSiPR 6, forming a signal F _T. The installation input of the timer of temporary states 10.1 is connected to an external input range tina. The input of the register 10.5 is connected to the control output of the FCR 7, forming a signal E _To . Moreover, the system is configured to enter the “Descent” command to the input “Set 1” of trigger 10.7.

In LST with an increased range of operating ranges, the control input of the constant bias code calculator 10.6 is connected to the control output of the BFSiPR 6, which generates a range switching signal U _L.

LST works as follows.

The operation of the LFW is considered by the example of its placement on a ground installation, in this regard, the vertical displacement (excess) Kφ is selected when the center of the laser raster is located above the line of sight of the target.

When applying to the electronic control unit LST (Fig. 1) an external Start command, the laser 1 is turned on and the initial parameters of all blocks are set. When the “Descent” command is sent to BFSiPR 6 after a time ΔТ, during which the controlled object reaches the initial control range L ₀ , BFSiPR 6 starts to operate in the mode of changing the parameters of the laser raster. It generates during the time interval Δt _{i the} codes of the angular dimensions of the raster M _K , the codes of the signs of the raster type R _K , the number of lines N _S and other service commands. Consistently connected with BFSiPR 6 FKR 7 generates binary codes z _t and y _t defining the scanning path of the laser beam in the raster. In FCC 10, vertical displacement (excess) codes Kφ are generated. Thus, binary codes z _t and y _t are supplied to the inputs of adder 8 from the outputs of the raster 7 code generator and the vertical displacement (excess) codes Kφ from the output of the FCC 10, which vary in time depending on the distance to the target. The adder 8 is made in such a way that at its outputs connected to the inputs of the DSCH 9, codes z _c = z _{t are formed} . y _c = y _m + Kφ, which determine the vertical displacement (excess) of the center of the laser raster over the line of sight of the target. Codes z _c and y _c , filed in the DSCH 9, are converted into time-tunable high-frequency control signals fz _c and fy _c . These signals are supplied to OECS 4 and determine the dimensions of the laser control raster and the position of its center relative to the line of sight of the target.

In FCC 10, vertical displacement (excess) codes Kφ = F (L) are generated as follows (Fig. 4).

When LST is turned on, pulses with a frequency of F _T are received to the second input of the logic circuit “I” 10.8 from the control output of the BFSiPR 6, and clock signals E _K , which appear at the end of the next frame of the laser raster and are used for recording, are sent to the input of the register 10.5 from FCR 7 in the internal registers BFSiPR 6 data on the parameters of the next frame. The clock pulses E _K are used to synchronize the entries in the register 10.5 of the data coming from the subtracting device 10.4, with the records of the frame parameters in BFSiPR 6.

Before starting the controlled object in the timer of temporary states 10.1, the distance L to the target is entered, while taking into account the variable and the known speed of the controlled object, the flight time to the target is equal to T _K.

After the “Descent” command is entered into the BFSiPR 6, it starts to operate in the mode of changing the laser raster parameters, and the “Descent” command issued from the output of the BFSiPR 6 to the “Set 1” input of trigger 10.7 sets the output of trigger 10.7 to a state with a high output level thereby allowing 10.8 pulses of the clock frequency F _T to pass through the logic circuit “AND” to the timer of temporary states 10.1, the calculator of the normalized alignment curve 10.2, and the calculator of constant offset codes 10.6. The constant offset code calculator 10.6, when fed to the clock signal F _T , calculates the constant vertical offset (exceeding) code h ₀ (t _n ) over the time interval Δt _i , under the influence of which the center of the laser raster is located above the line of sight of the target by the value of h ₀ (figa), while:

h ₀ (t _n ) = h ₀ · N / (L (t) φ _g Г _Т ), where

h ₀ - the value of the constant displacement (excess) of the center of the raster over the line of sight of the target;

N is the number of discrete frequencies generated by the two-channel frequency synthesizer 9, equal, for example, 8192;

φ _g is the maximum scanning angle of the deflector;

Г _Т - angular increase of the output telescope;

L (t) - current distance to the managed object.

The timer of temporary states 10.1 forms a strobe C _{Tr of the} beginning of combination (decrease) (Fig.4d) and a strobe C _{Tk of the} end of the LST operation (Fig.4e). The time of appearance of the strobe of the end of work With _Tk is determined by the established range L and the previously known speed of the controlled object in time. The dependence of the distance to the managed object from the time of its flight is conventionally presented in Fig.4c. The end gate C _Tk sets the trigger 10.7 to a state with a low output level, and the arrival of pulses of the clock frequency F _T through the logic circuit "And" 10.8 stops.

After the time T _r after entering the "Descent" command, the timer of temporary states 10.1 forms a strobe of the beginning of combination (decrease) With _Tr .

When the calculator of the normalized alignment curve 10.2 with the timer of temporary states 10.1 is supplied with a strobe of the beginning of alignment (decrease) With _Tr (Fig.4d), it generates a code h _cn (t _n ) in accordance with a given law, the value of which varies in the range from 0 to 1. The law of change of the alignment curve (reduction) is determined by the parameters of the managed object and can, for example, be presented in the form:

h _sn (t _n ) = 1st ^{-t / τ} , where

τ is a constant that determines the rate of combination (decrease),

t is the current time from the beginning of the combination (decrease).

In the general case, the value of the constant τ, which may be different for different types of controlled object (UO), is set by an external signal "UO type". This law determines the nature of the decrease in time of the linear mismatch Δh _{c, m of the} center of the laser raster relative to the line of sight.

Next, the codes of the normalized alignment (decrease) curve h _cn (t _n ) are supplied to the first input of the multiplier 10.3, the second input of which is supplied from the calculator of constant offset codes 10.6 by the constant vertical offset (excess) codes h ₀ (t _n ). After multiplying the two input codes at the output of the multiplier 10.3, the code h ₀ (t _n ) · h _cn (t _n ) is generated, which goes to the first input of the subtractor 10.4, the second input of which receives the code h ₀ (t _n ) from the constant code calculator displacements 10.6.

At the output of the subtractor 10.4 in the time interval t _n + Δt _i , a vertical displacement (excess) code is generated, which is supplied to the input of register 10.5 and determined by the formula:

Kφ = h ₀ (t _n ) · [1-h _sn (t _n )] · N / (L · (φ _g · Г _Т ).

Conditionally, the nature of the change in the code Kφ is shown in Fig. 4d.

At the moment of applying the signal E _K from FCR 7 to the input of the register register 10.5, the current values of the vertical displacement codes (excesses) Kφ presented by the subtractor 10.4 are recorded and stored in it until the next signal E _K arrives. These codes are then fed from the output of the FCC 10 to one of the inputs of the adder 8, which is designed in such a way that provides output codes z _c = z _t , y _c = y _t + Kφ.

The sampling time interval Δt _{i of} codes of constant vertical displacement (excess), as well as codes of a normalized alignment curve (decrease) is selected, for example, to be equal to half the time of formation of the information field (IP) frame, that is, when the update information on the coordinates in the IP is equal to 50 Hz (the time of the IP frame formation is 10 ms), the vertical displacement (excess) codes are changed through Δt _i = 5 ms.

Obviously, when h _cn (t _n ) is reached, equal to unity, Kφ = 0 and the center of the laser raster is aligned with the line of sight of the target. Conventionally, the nature of the change in the linear magnitude of the vertical displacement (excess) h _pr (t), the center of the laser raster over the line of sight of the target is shown in Fig.4b.

In LST with an increased operating range (figure 2) in BFSiPR 6 additionally generated a signal switching range U _L. When U _L = 1, a "near" control zone is formed, and a 5.1 telescope is connected with an increase in the _GB . At U _Л = 0, a “distant” control zone is formed, while a telescope 5.2 is connected with an increase in Г _ДЗ .

The work of the FCC 10 in such a LST coincides with the work of the LST described above, except that the constant offset code calculator 10.6 generates a constant vertical offset (excess) code h ₀ (t _n ) according to the following algorithm:

h ₀ (t _n ) = h ₀ · N / (L (t) φ _g Г _БЗ ), for U _Л = 1

h ₀ (t _n ) = h ₀ · N / (L (t) φ _g Г _ДЗ ), for U _Л = 0

The range switching control input U _L of the offset code calculator 10.6 is shown by a dotted line in FIG.

Depending on the choice of the guidance method, the adder 8 can be implemented as follows (figure 5). In the LST, intended for placement on a ground installation, when only the vertical offset (excess) of the center of the laser raster over the line of sight of the target is required, the adder 8 (figa) can contain only the adder 8.1, calculating the code z _c = z _t and y _with = y _m + Kφ. If the LST is designed to be placed on an air carrier and it is necessary to shift the center of the laser raster relative to the line of sight of the target to the right or left, the adder 8 (Fig.5b) may contain one controlled adder 8.1 that calculates the code z _с = z _t + Kφ, in this case _c = y _t. Moreover, when applying an external control signal, for example, U _Z = 0 to shift the center of the laser raster to the left, the code z _c = z _t + Kφ is calculated, and when applying an external control signal, U _Z = 1, to shift the center of the laser raster to the right, code z _c = z _t -Kφ.

In general, adder 8 contains two controlled adders 8.1 and 8.2 (Fig. 5c) that calculate the sum (or difference) of the codes z _c = z _t ϒ Kφ, for _c = y _t ϒ Kφ depending on the supply of an external control signal, for example , U _Z = 0 and U _Y = 0 to shift the center of the laser raster to the left and up, or, for example, U _Z = 1 and U _Y = 1 to shift the center of the laser raster to the right and down.

BFSiPR 6, FKR 10 and the adder 8 can be implemented on the basis of a number of microcontrollers, for example, ATMEL company T89C51AS2, containing non-volatile memory, control ports and timers.

As an AOI of an optical-electronic scanning system 4 of the proposed device, for example, an AOI with a light-sound conduit from an optically active anisotropic paratellurite crystal (TeO ₂ ) can be used, which scans laser beams of the visible and near-IR spectra and has a light aperture of up to 10 ... 15 mm Such deflectors can have a full scan angle of 3 degrees with a control frequency band of 32 MHz. If the two-channel frequency synthesizer 9 has a thirteen-bit control code in each channel, then it generates 8192 discrete control frequencies.

Thus, the introduction of a control unit vents adder and shaper offset codes so that the raster codes z _m and _m output driver raster codes and code Kφ offset from the output driver bias codes are supplied to the adder inputs, configured so that it the outputs connected to the inputs of the two-channel frequency synthesizer generate codes z _c = z _t , y _c = y _t + Kφ, or z _c = z _t + Kφ, y _c = y _t , or z _c = z + Kφ _t , y _c = y _t + Kφ, the connection of the control inputs of the displacement code generator with the control outputs of the forming unit clock signals and parameters of the raster and the raster code generator and the execution of the system with the ability to enter the “Descent” command to the input of the block for generating clock signals and raster parameters, increased the noise immunity of the LST when it is placed both on ground launchers and on an air carrier.
