Embodiment

[0056] A radar performance test evaluation method that does not require third-party data, see appendix figure 1 - attached image 3 As shown, the radar performance test evaluation method includes the following steps:

[0057] Collect intelligence data: obtain the distance, azimuth, altitude and time data in the radar equipment data;

[0058] Establish a motion model: set the position of the radar device as the coordinate origin, and at time t, its coordinate relative to the origin O is , without considering the random disturbance, the nth-order differential polynomial motion model of the target is:

[0059]

[0060] in, Indicates that the target is time coordinates, is the basic motion model expression of the moving target;

[0061] Nonlinear fitting: According to the motion model equation, the actual motion point trace of the target is solved, and the nonlinear motion track model and the actual motion track of the target are obtained through correlation fitting o...

Abstract

The invention discloses a radar performance test and assessment method without third party data. The method includes collecting information data, building a motion model, performing non-linear fitting, performing motion equation solving and non-linear fitting calculating, and performing data integration and comparison. The method overcomes the limitations that the conventional radar equipment performance assessment needs a third party to participate, and therefore, the function of self-test and self-assessment of radar equipment itself can be realized, and the BIT function of the radar equipment can be enhanced; and research findings can be used for radar performance assessment, and also used for developing and building models which are used for performance assessment of other parameters of the radar equipment.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a radar performance test and evaluation method without third-party data. Background technique [0002] Radar measurement accuracy is an important combat technical index of radar. In general, in order to check and evaluate whether the detection accuracy and system performance of a radar meet the design index requirements, the actual measurement method is generally used for testing. The basic method of the accuracy test is the comparison method, that is, using military aircraft as a cooperative target, flying according to a certain route, and installing differential GPS on the military aircraft to record the flight track as the true value, and the radar under test continuously tracks the target Measure, and then compare and count with the data recorded by differential GPS to find out the accuracy of the radar under test. [0003] Although the above method is relatively mature, it ha...
