Problems solved by technology

[0003] Existing field tests are costly and require a lot of manpower and material resources. The tests are complex and cannot be repeated. Once an error occurs, a huge price will be paid; secondly, only a single sampling test of a specific scene can be carried out, and various conditions cannot be traversed. , the success or failure of the test has no statistical significance, and the signal is very likely to be intercepted
The performance test of the radar altimeter simply through the field test can no longer meet the test and evaluation requirements of the radar altimeter

Abstract

The invention relates to a radar altimeter anti-jamming half-physical simulation system and method. The interference countermeasure scene control subsystem of the system is used to configure scene parameters, generate simulation parameters, echo parameters and jamming parameters; The echo parameters and interference parameters sent by the subsystem perform echo simulation and interference simulation to generate radio frequency signals; the radar altimeter test control subsystem is used to configure the parameters of the radar altimeter to be tested and collect the output data of the radar altimeter to be tested ; The anti-jamming performance inspection and evaluation subsystem is used to evaluate the anti-jamming performance of the radar altimeter to be tested according to the simulation data of the radar altimeter to be tested. The invention can reduce the test cost and improve the test accuracy.

Description

technical field [0001] The invention relates to the field of radar altimeter performance detection, in particular to a radar altimeter anti-jamming semi-physical simulation system and method. Background technique [0002] The radar altimeter is an important component of the airborne platform, and its anti-jamming performance directly affects the working performance of the platform. With the rapid development of electronic warfare technology, the anti-jamming performance of radar altimeters in complex electromagnetic environments and high countermeasures needs to be tested and evaluated urgently. [0003] Existing field tests are costly and require a lot of manpower and material resources. The tests are complex and cannot be repeated. Once an error occurs, a huge price will be paid; secondly, only a single sampling test of a specific scene can be carried out, and various conditions cannot be traversed. , the success or failure of the test has no statistical significance, and...
