In particular, since an algorithm for detecting a target from a simulated target is established, a direct launch test is unnecessary on an expensive unmanned vehicle, and a highly versatile performance test can be performed at a low cost. The present invention relates to a system and method for collecting a target reflected signal of a full-wave proximity fuse sensor.

In general, the proximity fuse detects the target target, obtains the location, velocity, and direction of information related to the target from the detected target, and obtains the optimal detonation time and aeration to maximize the warhead effect from the acquired information. The function of determining the direction is achieved.

In order to achieve this purpose, near-fuse, infrared, ultrasonic, visible light, laser or radio waves are used. In addition, as the various types of proximity fuses, their use characteristics are variously used depending on the operating environment, detection distance, and target type.

The propagation type proximity fuse sensor 100 is mounted on the moving vehicle 41 to transmit a signal to the simulated target 200 and collect the reflected signal of the simulated target 200, and in particular, the posture toward the simulated target 200 ( Combined with a position controller 43 having three axes (x, y, z) degrees of freedom such that rotation, up, down and deflection) are varied.

On the other hand, Figure 3 shows the flow of the simulation target reflection signal collection method of the radio wave proximity proximity sensor according to the present embodiment.

As shown, the simulated target reflection signal collection method of the propagation type proximity fuse sensor sequentially goes through the setting mode of S10, the operation mode of S50 and the target detection mode of S60, and then optimizes the propagation type proximity by using the result. Proceeds to the completion mode of S70 where the target detection algorithm of the fuse sensor is established.

When the setting mode of S10 is performed, it proceeds to the simulated target setting of S20, the unmanned sensor moving device setting of S30, and the driving guide line setting of S40.

The simulated target setting of S20 is the installation work of the aerial target support made in S21, and the unmanned sensor shifter setting of S30 is a radio wave type proximity fuse sensor made in S31, an image camera made in S32, a distance meter made in S33, and data made in S34. Installation work of the recording apparatus.

The driving guide line setting made in S40 refers to an operation of installing the unmanned sensor moving device on the driving guide line.

4 illustrates a state in which a simulated target setting of S20, an unmanned sensor moving device setting of S30, and a driving guide line setting of S40 are made.

As shown, the simulated target device 30 having completed setting is installed as a simulator 10, and the simulated target 200 uses the adjuster block 31 and the plurality of position strings 32 to support the target support 15. Installed with In this initial setting state (A), the simulation target 200 is suspended in the air with a ground height Ha of a predetermined height from the driving guide rail 20 laid on the bottom of the simulator 10.

At this time, in the initial setting state (A) of the simulated target 200, the ground clearance (Ha) and posture (rotation and deflection) are fixed to a specific value.

In addition, the unmanned sensor moving device 40 in which the setting is completed is located on the driving guide rail 20 on which the moving vehicle 41 is laid on the bottom of the simulator 10, and the data recording unit 42 is connected to the moving vehicle 41. , The position controller 43, the image wireless receiver 44, the target image camera 46, the range finder 47, and the radio wave type proximity fuse sensor 100 are mounted together, and the battery 45 is supplied with power. It is set to.

At this time, the posture (rotation, up and down and deflection) is fixed to a specific value in the initial setting state (a) that the radio wave type proximity fuse sensor 100 has for the simulated target 200.

In addition, the simulator imaging camera 50 is installed at a position spaced apart from the driving guide rail 20 so that the simulator 41 and the simulated target 200 can be photographed from the side, so that the vehicle 41 is simulated. The entire process of moving toward 30 may be captured and recorded as a side image.

On the other hand, in the operation mode of S50 it is checked whether the radio wave type proximity fuse sensor is moved at a set speed, and whether the encounter situation between the radio wave type proximity fuse sensor and the simulated target can be properly generated.

When the propagation type proximity fuse sensor is moved toward the simulated target device 30 as in S51, it is determined whether the approach speed of the propagation type proximity fuse sensor is set to the set speed as in S52.

In this case, the approach speed setting value of the propagation type proximity fuse sensor is based on 1m / s to 3m / s. However, according to the experimental conditions, the approach speed setting value can be changed to various values.

Referring to FIG. 4, in the movement of the propagation type proximity fuse sensor, the moving vehicle 41 approaches the simulation target device 30 along the driving guide rail 20, and the propagation type proximity fuse sensor 100 mounted thereon is also illustrated. By moving together with the moving vehicle 41, the movement of the radio wave type proximity fuse sensor 100 is realized. At this time, the approach speed of the moving vehicle 41 is 1m / s to 3m / s.

In S52, it is determined whether the radio type proximity fuse sensor moves with an approach speed of 1 m / s to 3 m / s. If the approach speed is less than 1 m / s or exceeds 3 m / s, the approach is made as in S53. Adjust the speed from 1m / s to 3m / s. This is done by controlling the driving force of the moving vehicle 41.

S54 is a process of determining whether the proximity proximity fuse sensor encounters a simulated target during the movement of the proximity proximity fuse sensor. In this process, when the simulation target is recognized by the proximity proximity fuse sensor, the target detection mode of S60 is immediately detected. However, if the simulated target is not recognized by the proximity proximity fuse sensor, the setting of the simulation target or the proximity proximity fuse sensor is immediately readjusted.

S55 is a process of readjusting the setting state of the mock target, through which the ground height and posture (rotation, up and down and deflection) of the mock target may be changed from the initial setting.

Referring to FIG. 4, in the readjustment of the setting state of the mock target, the height of the adjuster block 31 is controlled so that the ground height of the mock target 200 is higher or lower than the initial ground height, and the mock target 200 is further reduced. Posture (rotation and deflection) may also vary from the beginning. As a result of such adjustment, the simulation target 200 can be changed from the initial setting state A to the setting change state B. FIG.

At this time, even in the setting change state B of the simulation target 200, the ground clearance Hb and the posture (rotation and deflection) are fixed to a specific value.

S56 is a process of readjusting the setting state of the full-wave proximity fuse sensor, through which the attitude (rotation, up-down, deflection) of the full-wave proximity fuse sensor may be changed from the initial setting.

Referring to FIG. 4, in the readjustment of the setting state of the full-wave proximity fuse sensor, the full-wave proximity fuse sensor 100 coupled to the position controller 43 is controlled by controlling the position controller 43 provided in the moving vehicle 41. Posture (rotation, up and down, deflection) can be changed differently. This is because the position controller 43 is coupled to the propagation type proximity fuse sensor 20 with three axes (x, y, z) freedom.

At this time, the posture (rotation, up and down and deflection) is fixed to a specific value even in the change setting state b of the radio wave type proximity fuse sensor 100 with respect to the simulated target 200.

On the other hand, S60 is a target detection mode, which is performed by the radio type proximity fuse sensor irradiating the radio wave toward the simulated target and collecting the reflected signal while the radio type proximity fuse sensor is encountered with the simulated target.

In this embodiment, the target detection mode is completed by circulating the traveling guide rail once, and in this single cycle, the reaction signal recording process of S61 and the analysis and determination process of S62 are performed.

In the reaction signal recording process of S61, all the experimental processes are taken, collected and recorded. For this purpose, recording using the image camera of S61-1, measurement using the rangefinder of S61-2, and data recording of S61-3. Recording with the device is performed.

Referring to FIG. 4, in the reaction signal recording process, the setting state (A or B) is set on the target support 15 in the propagation type proximity fuse sensor 100 mounted on the moving vehicle 41 and set to the setting state (a or b). Radio waves are irradiated toward the simulated target 200 set as, and the reflected signal reflected from the simulated target 200 is collected.

Therefore, the image information includes the side images of the simulated target 200 and the moving vehicle 41 photographed using the simulator image camera 50, and the propagation type proximity fuse sensor 100 photographed using the target image camera 46. Both antenna beam irradiation direction images may be obtained, which are collected via the image wireless receiver 44.

In addition, the distance information is measured and collected by the traveling direction distance of the moving vehicle 41 toward the mock target 200 so that the target reflection signal collected by the propagation type proximity fuse sensor 100 is collected together with the distance. This is implemented through the laser of the range finder 47.

In addition, the data record includes all information transmitted from the target video camera 46, the simulator video camera 50, the range finder 47, and the radio wave type proximity fuse sensor 100, which are stored in the data recorder 42. do.

In the analysis and judgment process of S62, all the collected information is analyzed, and the judgment based on the analysis result is performed. All of these processes are displayed and verified in real time, allowing the experimenter to get quick experimental results.

On the other hand, S63 is a process in which the moving vehicle cycles the driving guide rail once to determine whether retesting is necessary after the experiment is completed. Repeat the experiment with the same procedure after setting the type proximity fuse sensor.

On the other hand, if re-testing is not necessary, the experiment is completed by switching to the completion mode of S70, and the analysis and judgment data obtained from the experimental results, such as S71, are applied to the design of the target detection algorithm implemented in the radio type proximity fuse sensor. .

Therefore, the target detection algorithm optimized for the actual target can be applied to the propagation type proximity fuse sensor based on various experimental target encounter situations.

5 shows a situation where a radio wave proximity proximity sensor equipped with an optimized target detection algorithm through an experiment according to the present embodiment encounters a real target.

As shown, when the missile 100A encounters the missile 200A, the full-wave proximity fuse sensor 100 mounted on the missile 100A may effectively remove the missile 200A by using a target detection algorithm. Optimum explosion conditions are identified.

The optimum explosive conditions are warhead fragments (b) of the missile (100A) when the missile (100A) is exploded in the state in which the propagation proximity (200) is effectively detected using the fuse antenna pattern (a) of the propagation type proximity fuse sensor (100). Means the detonation position (c) from which the missile 200A can be effectively destroyed.

Therefore, the propagation type proximity fuse sensor 100 grasps the optimum detonation position (c) from which the target missile 200A can be effectively destroyed from the target detection algorithm, and the warhead of the missile 100A in accordance with the detonation position (c). The explosion accuracy greatly increases the destruction accuracy of the missile 200A.
