Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

In order to improve the tracking performance of the guided weapon, it is necessary to develop an algorithm that avoids deceit and traces the target if the target such as aircraft, helicopter, etc. is located at the same viewing angle. An apparatus that can test this in a laboratory is an IR target signal simulator apparatus according to an embodiment of the present invention. The infrared simulator-only signal simulator according to the embodiment of the present invention can be used for the algorithm conformance test by simulating the characteristics and the trajectory of the simulator.

First, the configuration of the infrared simulator-only signal simulator according to the embodiment of the present invention will be described.

1, the apparatus for simulating an infrared target only signal according to an embodiment of the present invention includes a degeneracy light source 10, a filter unit 20, a condenser lens 30, a degenerate light size adjuster 40, A numerical controller 50, a reflector 60, and a planar mirror 70.

The degenerate light source 10 has a function of generating a degenerate light for devising a target missile (IRCM: Infra Red Counter Measure). According to Planck's curve, a high-temperature object has a maximum amount of light in the near-infrared wavelength band and a small amount in the infrared band, considering the mounting space of the object, but the physical size is smaller than that of the infrared wavelength band of the target object Is a degenerate light. Therefore, in order to generate the degenerate light source 10, a heating element having a high temperature of 1000 degrees or more must be produced.

The degenerative light source 10 uses a filament for emitting heat at a high temperature and is filled with an inert gas after vacuum to prevent oxidation. The filament temperature is set to be 2 times or more larger than the target light quantity in the infrared ray band of the target, and filament is produced. Set the filament temperature by measuring the flare temperature in the outdoors. In addition, a transmissive window (sapphire) capable of transmitting a near infrared ray and a medium infrared ray band is used so that a sufficient target signal is generated in the filament. The degenerative light source 10 should be designed to generate heat including infrared light among near infrared rays in order to generate an infrared signal only by irradiating the degenerate light.

As shown in Fig. 2, the deodorant light source 10 is installed inside the case 11. Fig. The deodorant light irradiated from the deodorant light source 10 can be irradiated through the outlet 12 provided in the case 11. By installing the deodorant light source 10 inside the case 11, it is possible to irradiate the deodorant light to a desired place.

The filter unit 20 serves to attenuate the ghost light uniformly in a near-infrared or medium-infrared wavelength band. The filter unit 20 may be a filter (Neutral filter or Spectral filter) that attenuates the degenerative light source constantly in two wavelength bands of near-infrared and mid-infrared. The filter unit 20 selects a filter that is a constant attenuation with respect to the infrared wavelength band including the wavelength band of the target. It is designed to be able to insert a spectral filter having different wavelength transmission characteristics according to the wavelength band if necessary so that it can simulate specific atmospheric transmission characteristics such as fog.

3 and 4, the filter unit 20 may include a plurality of neutral filters. The filter unit 20 may include a first neutral filter 21 and a second neutral filter 22. The first neutral filter 21 and the second neutral filter 22 are installed on the lens frame 23 together with the condenser lens 30. The first neutral filter (21) and the second neutral filter (22) are sequentially arranged on the movement path of the ghost light. The first neutral filter 21 and the second neutral filter 22 function to uniformly attenuate and transmit the light in the wavelength band of near and medium infrared to simulate the atmospheric transmission according to the outdoor environment. The first neutral filter 21 and the second neutral filter 22 employ two filters 21a and 22a, respectively. When the two filters are applied, the attenuation ratio of the beam can be easily adjusted by varying the transmission coefficient of the neutral filter.

The condenser lens 30 serves to reduce the diffusion along the optical path between the light source 10 and the neutral filter. The condenser lens 30 causes the imaging light to be imaged. The condensing lens 30 functions to assemble various filters or a space for fabrication between the defective light source and the defocused light, and also to reduce and enlarge the deflected light up to the deflected light size regulator 40. [

As shown in Figs. 3 and 4, the condenser lens 30 is located in the path of the degenerative light after the filter unit 20. The condenser lens 30 is installed in the lens frame 23. [ The condensing lens 30 functions to move the deodorizing light passing through the first and second filters 21 and 22 to a predetermined position in order to ensure easiness of arrangement of the optical system. The light tends to diffuse under the general condition, and in order to converge the light at a constant ratio with respect to the incident light, the condensing lens 30 is provided so as to converge the light incident on the condensing lens 30 to a certain distance of 1: 0.7 or 1: The lenses must be arranged into one body.

Meanwhile, a rotation neutral filter 24 may be provided between the condenser lens 30 and the degenerative light size adjuster 40. The rotation neutral filter 24 is installed in a degenerative light movement path following the condenser lens 30. The rotation neutrality filter 24 functions to facilitate characterization of the target only in accordance with various types of beam attenuation.

As shown in Figs. 5 and 6, the rotation neutral filter 24 is mounted radially in a circular structure with each filter having different attenuation characteristics. The rotary neutral filter 24 is designed to rotate the circular mechanism to replace the filter 24a.

The degenerate optical intensity adjuster 40 is disposed in the optical path of the next merge only after the rotation neutral filter 24. The degenerate light size adjuster 40 functions to simulate whether the deception signal is at a distance or a short distance. The degenerate optical size adjuster 40 is the focal plane on which the optical design and assembly adjustment of the equipment is based.

As shown in FIGS. 7 and 8, the photodetector 40 is provided with a hole group 41 in which individual holes 411 through which the light passes are arranged in a row. The hole groups 41 may be composed of a plurality of hole groups 41 arranged in a line and having individual holes 411 of different sizes.

For example, the degenerate light having passed through the individual holes 411 of the hole group 41 made up of the first large individual holes 411 on the left side in Fig. The degenerate light having passed through the individual holes 411 of the hole group 41 composed of the third small individual holes 411 from the left side of Fig. 8 can simulate the remote imperfections. The position of the hole group 41 can be adjusted by pushing or pulling the knob 43 provided on the deodorizer 40. [

As shown in FIGS. 7 and 9, the obfuscated optical number adjuster 50 is disposed on the front face of the defibrated optical size adjuster 40 in a superposed state. The trickle numeral adjuster (50) is provided with a cover (51). The upper and lower ends of the trickling optical number adjuster 50 move along the rail 42 disposed below and above the hole group 41 of the trickle light size adjuster 40. At this time, the cover 51 provided in the tamper-resistant optical number adjuster 50 controls the number of defective lights by preventing the light from passing only through the individual holes 411 constituting the hole group 41. The cover 51 should be designed so as to cover part or all of the individual holes 411. For this, the cover 51 is formed in a triangular structure.

The shield 51 may be sequentially shielded from individual holes 411 located at the lowermost end to individual holes 411 located at the uppermost end. This is possible because the structure of the visor 51 is a triangular structure having hypotenuse.

10, when the hole group 41 is constituted by four individual holes 411, the oblique structure of the triangular structure 51 having the hypotenuse forms the hole group 41 along the upper and lower rails 42, The lowest-stage individual holes 411 can be covered. When the shield 51 further moves, it is possible to cover two individual holes from the lowermost end to the second individual hole 411. [ When the visor 51 further moves, it is possible to cover three individual holes from the lowermost stage to the third individual hole 411. When the visor 51 further moves, all four individual holes can be covered up to the uppermost individual hole 411. In this manner, the number of the deflected lights can be controlled by preventing the light from passing only when the cover 51 covers the individual holes 411.

A mirror 60 and a plane mirror 70 are provided in the beam path after the trick optical number adjuster 50.

As shown in FIG. 11, the reflecting mirror 60 serves to direct the beam, which has passed through the plurality of individual holes 411, in the direction of the plane mirror 70. The reflector 60 may be a non-reticulated mirror or a stocked spherical mirror that implements parallel light for remote representation. The reflector 60 converts the aberration light into a parallel light. The reflector 60 is located at the focal distance of the equipment.

Specifically, the reflector 60 is located on a stock axis where the incident angle and the reflection angle do not coincide with each other, and is made of a non-axis lens to reflect the incident light as parallel light. The reflector 60 should be designed in a structure capable of horizontal, vertical rotation and horizontal movement for optical axis alignment and adjustment. In order to fabricate the reflector 60 as a stockpile, a large pore size is manufactured, and then a portion away from the center is used as the stocking distance. Precision cutting technology is required to fabricate the reflector 60 as a stockpile.

The plane mirror 70 changes the direction of the beam reflected from the reflector 60 and sends it to the beam splitter 300. The planar mirror 70 deflects the deflected light made of parallel light so that it can be in the same viewing angle as the target light. The planar mirror 70 functions to adjust the trajectory by operating with the speed adjustment and rotation device 90 of the degenerate light.

A scale for indicating the angle may be provided on the outer surface of the rotary part 91. A hollow portion 911 through which the stray light passes is provided in the rotary portion 91. The table 80 is placed on the upper surface of the rotation part 91. [ When the rotary part 91 rotates, the table 80 rotates at the same time.

The bottom portion of the rotation part 91 is rotatably supported in the fixing part 92. The fixing portion 92 serves to stably support the rotation portion 91. [ Inside the fixing portion 92, a hollow portion 911 through which the stray light passes is provided.

The bearing portion 93 is positioned between the rotation portion 91 and the fixing portion 92. The bearing portion 93 serves to smoothly rotate the rotation portion 91. [

A rotation control device 94 is provided at one side of the fixing portion 92. The rotation control device 94 serves to stop the rotation part 91 of the circular ring shape when rotating at a specific angle. Specifically, the rotation control device 94 causes the rotation part 91 to stop at an angle of 90 degrees.

The rotation control device 94 includes a main body 941 and a rod 942. The main body 941 is provided on one side of the fixing portion 92. The rod 942 is coupled to the body 941. The distal end 943 of the rod 942 protrudes from the body 941. A portion of the distal end 943 of the rod 942 is inserted into the insertion groove 912 provided on the outer circumferential surface of the rotary portion 91. The tip 943 portion of the rod 942 may be a roller. When the leading end 943 of the rod 942 is a roller, the corresponding insertion groove 912 of the rotation part 91 is also formed as a groove corresponding to the roller. The rear end of the rod 942 is coupled to the inside of the body 941 while being supported by the elastic member 944. [ The elastic member 944 may be a spring.

The beam splitter 300 sends the deodorized light irradiated from the flat mirror 70 to the meter 200. The meter 200 includes a visible area band meter for optical alignment of the optical device and an infrared band meter for precision verification. Since the beam splitter is a known device, detailed description of the configuration is omitted.

And irradiates the target light 100 from behind the beam splitter 300. The target light 100 is irradiated to the measuring device 200 through the beam splitter 300. The meter 200 may be a lens. 2 and 3 and the target light 100 irradiated to the meter 200 are displayed on the monitor screen connected to the meter 200 as points such as a tamper signal and a target signal. Debris (1, 2, 3, 4) simulates a degenerate object falling from a target such as an aircraft, helicopter, The target light 100 simulates targets such as aircraft, helicopters, and the like.

Hereinafter, the operation of the infrared simulator-only signal simulator according to the embodiment of the present invention will be described.

The temperature of the exhaust gas of the aircraft, which is the target of infrared-guided weapons, is about 300 degrees, and the peak wavelength band is the medium-wave infrared band. High-temperature objects radiate the maximum amount of light in the short-wavelength infrared (near-infrared) band, as confirmed by the Planck curve (temperature-dependent wavelength and light intensity graph), but also contain much light in the medium-wave infrared (mid infrared) band. The aircraft should use a small, high-temperature flare (flare) in order to load the aircraft in a small space of the aircraft while emitting light in the medium-wave band larger than the target and release it if necessary.

In order for infrared-guided weapons to track and shoot down the exhaust gas temperature of an aircraft, it is necessary to be able to detect and track the mid-wave band with a peak light intensity. On the other hand, aircraft must be capable of avoiding infrared-guided weapons by fast-accelerating maneuvers faster than guided weapons, or by generating false signals (deception) that can avoid tracking of infrared-guided weapons.

In order for an aircraft to avoid an infrared-guided weapon in the medium-wave range, it is ideal to use a high-temperature small de- vice as mentioned above, and the amount of light of the same wavelength band larger than that of the medium- It should be made. Infrared-guided weapons are designed to track the amount of light in the same wavelength band. Infrared-guided weapons use a variety of tracking algorithms to track targets and respond to deceptive signals, so the flare also avoids infrared-guided weapons by a variety of deceptive trajectory and dropping methods.

The embodiment of the present invention provides an infrared target simulator signal simulator for use in testing and algorithm development in performance of avoiding a signal only when a target and a deaf object are tracked and a deception signal is generated in various environments in a laboratory. In order to realize a signal simulator for infrared target only, a light source capable of generating a high-temperature deformation signal including a wavelength band of the target, a transmittance simulation according to the atmospheric environment, a filter for attenuating the infrared wavelength band constantly, , It is necessary to be able to simulate the release count of deceit, the deceit trajectory and the release time.

As shown in FIGS. 1 and 14, the degenerate light generated in the degenerative light source 10 attracts degeneracy light to the individual holes 411 of the degeneracy light size adjuster 40 using the condenser lens 30 according to the structural arrangement characteristics of the equipment come. The degenerative light (1, 2, 3, 4) diffused by the degenerate light size adjuster 40 is reflected by the reflector 60 and converted into parallel light. The deflected light converted into the parallel light is reflected by the flat mirror 70. The deflected light reflected by the flat mirror 70 is reflected to the beam splitter 300 through the hole 81 of the table 80 and the hollow portion 911 of the rotating device 90.

The deflected lights 1, 2, 3 and 4 reflected on the beam splitter 300 enter the visible light or infrared band meter 200. At this time, the target light 100 is incident on the beam splitter 300 together with the deflected lights 1, 2, 3, 4. The deflected lights (1, 2, 3, 4) and the target light (100) incident on the beam splitter (300) (100) is represented as a target signal so that two types of optical characteristics can be compared.

FIG. 15 is a diagram showing a movement trajectory of a false signal image on a monitor screen according to a rotation angle when a table is rotated by a rotation device. Specifically, in the case of 0 degree at which the original table 80 is not rotated, the ghost lights (1, 2, 3, 4) indicating the ghost signals are vertically displayed in the upper area on the monitor screen. When the table 80 is rotated by 90 degrees, the jiggling lights 1, 2, 3 and 4 indicating the jiggling signal are horizontally displayed in the left area on the monitor screen. When the table 80 is rotated by 180 degrees, the diaphragm lights 1, 2, 3 and 4 indicating a tamper signal are horizontally displayed in the lower area on the monitor screen. When the table 80 is rotated by 270 degrees, the diopter lights (1, 2, 3, 4) indicating a tamper signal are horizontally displayed on the monitor screen.

When the table 80 is rotated around the rotary device 90 as described above, the defective light source 10, the filter unit 20, the condenser lens 30, The positions of the deception signal image are changed by the rotation of the optical size adjuster 40, the diopter optical number adjuster 50, the reflector 60, the plane mirror 70, and the like.

10, when the number of deception signals is to be adjusted, the diopter optical number adjuster 50 is moved in the direction of the hole group 41 to cover the individual holes 411 with the cover 51. [ As shown in FIG. 10, when two individual holes 411 of the four individual holes 411 are covered by the shield 51, only two pieces of the individual holes 411 pass through, and only two false signals are displayed on the monitor screen do.

As described above, the IR signal simulator according to the embodiment of the present invention can perform a test in the room by realizing the characteristic according to the air permeability of the deception signal in the room, the implementation of the remote image, and the trajectory of the deception signal. In addition, it is possible to improve the searcher - only avoidance function by implementing the explorer tracking algorithm using the test results and applying the deaf signal characteristics to the test apparatus in the actual outdoor environment.
