Abstract

The invention relates to the field of radar countermeasure device performance evaluation and measurement and particularly relates to a radar analog echo and interference signal measuring device. The application requirement of a radar countermeasure device performance evaluation test that a completely coherent radar analog echo signal can be generated in a low-cost manner, the amplitude and delay of the echo signal can be adjusted, different distances and target echoes with different sizes can be simulated, an interference signal and an echo signal can be mixed, dechirp processing is carried out to generate an intermediate frequency signal, the intermediate frequency signal is sampled and stored at a high speed, and a radar signal processing terminal is used for performing data analysis ismet, and the problem that a large number of test devices suitable for product debugging and used by testers are configured on a production line in the development and production process of the radar countermeasure device is solved.

Description

technical field [0001] The invention belongs to the technical field of performance evaluation and measurement of radar countermeasure devices, and in particular relates to a radar simulation echo and interference signal measurement device. Background technique [0002] In the development and production process of radar countermeasure devices, it is necessary to generate radar analog echo signals and inject them into radar jamming signals, and after digitization, they will be processed by the radar signal digital processing terminal to evaluate the effectiveness of radar countermeasures. However, most of the current equipment that realizes the above functions is composed of expensive general-purpose instruments, which are only suitable for use by professionals in the laboratory, and are not suitable for mass configuration on the production line by product debugging and testers. Therefore, there is a need for a radar analog echo and interference signal measuring device suitabl...
