Radar performance test and assessment method without third party data

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...

Problems solved by technology

[0004] 1) Restricted by factors such as flight mobilization and air traffic control;

[0005] 2) Large investment, high cost, and difficult implementation;

[0006] 3) The evaluation organization is complicated and the observation cycle is long;

[0007] 4) Affect test progress and troop training tasks;

[0008] 5) Not suitable for radar delivery troops and overhaul depots

[0009] These deficiencies seriously limit its wide application, and at the same time, it also raises a new technical problem for us: can we find a simple and effective method to check and calibrate radar, and at the same time, it is easy to be mastered and implemented
