Description

Technical Field

[0001] The invention relates to a photoelectric radar integrated reconnaissance equipment testing and calibration system, belonging to the technical field of testing. Background Art

[0002] As a complex, high-precision instrument, optical SAR pods require comprehensive functional testing using a variety of equipment. Currently, there is no dedicated test setup that integrates multiple test instruments specifically for optical SAR pod testing. In actual optical SAR pod testing, test equipment is often lost or damaged, significantly reducing testing efficiency. Summary of the Invention

[0003] The technical problem solved by the present invention is to overcome the deficiencies of the prior art and propose a photoelectric radar integrated reconnaissance equipment testing and calibration system to provide protection for the test equipment, improve test efficiency and reduce labor costs.

[0004] The solution of the present invention is:

[0005] A photoelectric radar integrated reconnaissance equipment testing and calibration system, including a display screen, a test chassis, a data transceiver module, a data analysis module, a video processing module, an inertial group module, a microwave generation module and a power supply module.

[0006] The display screen is connected to the test chassis via an HDMI high-definition data cable, and displays the visible light camera and infrared thermal imager video images output by the pod in real time;

[0007] The three-phase plug 1 on the outside of the power module is connected to the 220V mains power supply. The power module is internally connected to the test chassis, the inertial group module, and the power supply port of the power module to power the test equipment.

[0008] The data transceiver module is connected to the test chassis. The data transceiver module leads to the aviation plug 2 outside the device, which is plugged into the control test cable of the optical SAR pod to complete the test chassis sending control commands to the optical SAR pod and receiving the status information of the optical SAR pod;

[0009] The data analysis module is connected to the test chassis. The data analysis module leads to the aviation plug 3 outside the device, and the program test cable of the optical SAR pod is plugged in;

[0010] The video processing module is connected to the test chassis via an Ethernet interface, and an aviation plug 4 is led out of the device to plug in the video test cable of the optical SAR pod;

[0011] The inertial group module is connected to the test chassis to provide inertial group data for the test of the optical SAR pod;

[0012] The microwave generation module provides the signal source for the radar pattern and zero error calibration of the optical SAR pod.

[0013] Furthermore, when the optical SAR pod system completes the command function test:

[0014] The data transceiver module of the test device is internally connected to the test chassis and the inertial group module, and externally connected to the aviation plug 2, which is connected to the control test cable of the optical SAR pod. The inertial group module transmits the inertial group data to the optical SAR pod through the data transceiver module, providing the necessary inertial group data for the functional test of the optical SAR pod. At the same time, the test chassis sends the control instructions to the optical SAR pod through the data transceiver module to realize the instruction transmission. The optical SAR pod transmits the status information to the test chassis through the receipt transceiver module to realize status feedback.

[0015] Furthermore, during the internal program verification of the optical SAR pod:

[0016] The data analysis module of the test device is connected to the test chassis internally, and is externally connected to the aviation plug 3, which is plugged into the program test cable of the optical SAR pod. Each embedded system inside the optical SAR pod transmits its own program-related data to the data analysis module.

[0017] Furthermore, when testing the optical SAR pod video image function:

[0018] The video processing module of the test device is internally connected to the test chassis and externally connected to the aerial plug 4, which is plugged into the video test cable of the optical SAR pod. The video data output by the optical SAR pod is parsed into an H.264 format data stream by the video processing module and then input into the test chassis. Finally, the video images of the visible light camera and infrared thermal imager are displayed in real time on the display screen.

[0019] Furthermore, when the radar pattern and zero position of the optical SAR pod are corrected:

[0020] Adjust the microwave generating module to face the radar antenna in the optical SAR pod, set the module to generate Ka-band microwaves, control the optical SAR pod to align with the microwave generating module, record the azimuth and elevation angles at this time, and after setting the parameters, control the optical SAR pod to enter GMTI mode and record the returned data.

[0021] Furthermore, the video processing module parses the real-time video output by the optical SAR pod into a data stream in H.264 format and transmits it to the test chassis.

[0022] Furthermore, the data analysis module inserts the program test cable of the optical SAR pod to complete the inspection and update of the internal program of the optical SAR pod.

[0023] Furthermore, if a program error occurs or the version needs to be updated, the latest program can be downloaded to the embedded systems inside the optical SAR pod via the test chassis and data analysis module to complete the update of the internal program of the optical SAR pod.

[0024] Furthermore, Matlab software is used to analyze data in the test chassis to calculate the radar zero-position error, radar pattern K value, and phase. The processed parameters are then updated to the optical SAR pod-related embedded system through the data analysis module to complete the radar pattern and zero-position correction.

[0025] Furthermore, after module analysis and verification, the results are sent to the test chassis to complete program verification.

[0026] The beneficial effects of the present invention compared with the prior art are:

[0027] The present invention can not only provide a certain degree of protection for the test equipment, save the test personnel the work of setting up the test environment, and improve the test efficiency, but also provide great convenience for the test personnel in the field during the equipment transportation.
