Abstract

The invention relates to an ultra-wideband radar target echo signal simulation method and simulator based on dynamic reconfigurable DRFM, and belongs to the technical field of radar. By adopting the method and the simulator of the present invention, since it realizes the dynamic configuration of sub-channels through dynamic estimation, it is not necessary to perform full-channel processing on the ultra-wideband radar transmission signal, which optimizes the dynamic utilization of hardware resources, and can be used in existing applications. On the basis of the hardware platform, high-fidelity dynamic reconstruction is performed for different application scenarios through amplitude and phase compensation technology, thereby realizing the ultra-wideband radar target echo simulation based on dynamic reconfigurable DRFM for ultra-wideband radar, and the present invention The realization method is simple, the application range is wide, and the realization cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to the technical field of radar target echo signal simulation, in particular to an ultra-wideband radar target echo signal simulation method and a simulator. Background technique [0002] With the continuous development of new system radar and electronic warfare technology, people have higher and higher requirements for radar performance in practical applications. The pursuit of radar performance is mainly reflected in the pursuit of radar resolution capabilities, followed by the development of radar operating bandwidth from narrowband mode to broadband mode. Now, the working bandwidth of radar is further developed from broadband mode to ultra-wideband mode. Today, the bandwidth of many new radars has been developed to the ultra-wideband mode. Therefore, the radar target echo simulator must realize the processing of ultra-wideband radar signals. As the core technology of radar targ...
