Anti-interference semi-physical simulation system and method for radar altimeter

Abstract

The invention relates to an anti-interference semi-physical simulation system and method for a radar altimeter. An interference confrontation scene control subsystem of the system is used for configuring scene parameters and generating simulation parameters, echo parameters and interference parameters; an echo simulation and interference unit subsystem is used for performing echo simulation and interference simulation according to an emission signal of a to-be-tested radar altimeter and the echo parameter and the interference parameter sent by the interference countermeasure scene control subsystem to generate a radio frequency signal; a radar altimeter test control subsystem is used for configuring parameters of the to-be-tested radar altimeter and collecting output data of the to-be-tested radar altimeter; and an anti-interference performance test and evaluation subsystem is used for evaluating the anti-interference performance of the to-be-tested radar altimeter according to the simulation data of the to-be-tested radar altimeter. The test cost can be reduced, and the test accuracy can be improved.

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...

[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
