The utility model discloses in, reflection prism adopt the pyramid prism, this prism has former retro-reflective characteristics, reflected beam and incident beam are parallel promptly, the incident light on arbitrary space direction, the reflected beam shows the characteristic that returns for former way, uses this kind of prism can be effectively with the former way reflection of laser that the shooting came back supply it to handle, and this prism reflection loss is little, reflection laser energy intensity is big.

The utility model discloses in, still included codec, codec is connected with laser receiving lens cone with the laser emission lens cone, and codec decodes laser receiving lens cone received signal, and the signal after will handling is sent by the laser emission lens cone after encoding again.

The utility model discloses all set up laser transceiver and receiving terminal on each combat tank, the utility model discloses regard as the step explanation with a shooting flow, a combat tank has implemented a simulation strike to another combat tank in this flow, executes the combat tank of simulation strike and marks as shooter combat vehicle, bears the combat tank of simulation strike and marks as the target combat vehicle, and it has included following technical flow:

firstly, a shooting party combat vehicle emits a laser signal to a target party combat vehicle through a laser emission lens barrel, the laser signal is emitted towards the body of the target party combat vehicle, then a reflecting prism arranged on a receiving terminal of the target party combat vehicle reflects a part of the laser signal emitted by the shooting party combat vehicle back to the shooting party combat vehicle, and the laser signal is received by a laser receiving lens barrel.

The utility model discloses in, because reflection prism sets up on the stand, its quantity must be limited under the control of cost, if adopt conventional laser, then probably can't be reflected by reflection prism. Therefore, the laser used in the present invention is a laser beam with a large divergence angle, and the laser beam can cover the target and the reflecting prism. Meanwhile, each reflecting prism can reflect the laser within the angle range of 60 degrees in front, and the six prisms are combined to meet the requirement of reflecting the laser from 360 degrees around without any gap, as shown in fig. 3. Therefore, at least one reflecting prism on the upright post can be completely covered by the laser beam, and good reflection of the laser beam is realized.

The utility model provides a reflection prism adopt be the pyramid prism, this prism has former retro-reflective characteristics, and the reflected beam is parallel with incident beam promptly, and arbitrary space direction incident light, reflected beam show the characteristic that returns for former way. The prism can effectively reflect the laser shot by the combat vehicles of the shooter back, and the pyramid prism provides enough energy intensity to allow the long-distance laser receiving lens barrel to effectively receive and process the laser.

Then the laser signal received by the laser receiving lens barrel is sent into a coder-decoder, the coder-decoder decodes according to the information contained in the laser signal, carries out calculation such as distance measurement and angle measurement, codes the information, and sends a laser information beam again by using the laser emitting lens barrel, wherein the laser information beam is emitted towards a laser receiving probe of a target combat vehicle;

specifically, a laser receiving lens barrel in a laser transceiver is composed of an imaging lens and a two-dimensional photoelectric sensor. Laser points emitted from different positions far away are imaged into a small light spot on the two-dimensional photoelectric sensor through the lens, and the two-dimensional photoelectric sensor can output two-dimensional position information relative to the center of an imaging surface. The two-dimensional deviation angle of the photoelectric relative to the optical axis can be calculated by converting the position information. And meanwhile, the distance between the fighting vehicle of the transmitting party and the fighting vehicle of the target party is judged according to the time of laser emission and the time of laser receiving. And then the information is encoded through a decoding encoder and then is retransmitted to the target combat vehicle.

More specifically, when shooting, the aiming point, i.e. the optical axis point O, can calculate the positions dx and dy of the hit point O relative to the prism by measuring the distance and the deflection angle of the reference reflecting prism. The algorithm is as follows: and carrying out two-dimensional angle measurement on the distant reflection light spot P, measuring two direction included angles theta x and theta y of the reflection light spot P relative to the optical axis, and simultaneously measuring the shooting distance L according to the time difference of the returned laser.

Because the optical axis position represents the aiming point and the cannonball drop point, when theta x, theta y and L are measured, the accurate position of the optical axis point O can be calculated by taking the reflecting prism as a reference:

dx=θx*L

dy=θy*L。

and finally, after receiving the laser information, the laser receiving probe of the target party combat vehicle decodes the laser information, calculates the hit position by combining a three-dimensional entity size model of the target party combat vehicle, and further calculates an accurate damage result.

Generally, for a training weapon vehicle, the installation position of the receiving terminal is unchanged at the same designated position, i.e. the position of the receiving terminal, i.e. the position of the reflecting prism, is fixed. Therefore, the position hit by the opposite 'cannonball' during shooting training can be accurately calculated by inputting a three-dimensional solid simulation of the reflecting prism as a reference point.

In actual confrontational training, both parties of the battle are in a random state, and at this time, the target vehicle body cannot be aligned with the shooting direction, so that it is necessary to take all the directional postures in the three-dimensional space into consideration. When a full three-dimensional model of the target vehicle body is established, the orientation posture of the vehicle body and the geographic coordinates of both parties of engagement are acquired, comprehensive calculation can be carried out in a three-dimensional space of the ground, and the hit position and the incident angle data of the cannonball are obtained.

The satellite positioning module contained in the receiving terminal can acquire and record the geographic positions of both parties of the battle in real time according to longitude and latitude data. As shown in fig. 6: coordinate system EeN is the geodetic coordinate system, with N being true north 0 ° and E being true east 90 °. With the latitude and longitude data conversion values as coordinates, the shooter a is (e 1, n 1) and the target P is (e 2, n 2).

The firing direction Li can now be obtained as:

Li=arctan((e2-e1)/(n2-n1))

the vehicle body direction sensor can output the direction of the vehicle body in real time. And acquiring a value pt of the vehicle body pointing data through data acquisition.

The incident angle r of the projectile is:

r=pt–Li

in an actual three-dimensional space, a physical three-dimensional model of the target vehicle body is established by using a coordinate system PXYZ with the reflecting prism P as an origin, and the position data of the hit point O on the surface of the vehicle body can be further calculated according to the incident angle r, the angle measurement data and the distance measurement data.

After the position and incident angle data of the vehicle body impact point are obtained, an accurate target damage result can be obtained after processing and operation according to the type of the shell used by a shooter.

The utility model discloses in, do and install the direction that automobile body attitude sensor was used for measuring automobile body and gun turret additional, after the gun turret takes place to rotate, still can be accurate carry out the calculation of relevant hit point like this.
