Problems solved by technology

However, in the prior art, due to the high sampling rate of ultra-wideband radar signals and the large amount of data, the difficulty of processing ultra-wideband radar signals also increases accordingly
On the existing hardware platform, the traditional DRFM design is not enough for the processing of UWB radar signals

Abstract

The invention relates to an ultra-wideband radar target echo signal simulation method and a simulator based on a dynamic reconfigurable DRFM, which belong to the technical field of radars. By adoptingthe method and the simulator disclosed in the invention, dynamic configuration of the sub-channels is realized through dynamic estimation, therefore, full-channel processing is not required to be performed on the ultra-wideband radar transmitting signal, the dynamic utilization of hardware resources is optimized, further, on the basis of an existing hardware platform, high-fidelity dynamic reconstruction is carried out on different application scenes through an amplitude-phase compensation technology, so that dynamic reconfigurable DRFM-based ultra-wideband radar target echo simulation oriented to the ultra-wideband radar is realized, and the implementation method is simple and convenient, wide in application range and relatively low in implementation cost.

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 working bandwidth from narrowband mode to wideband mode. Now, the working bandwidth of the radar has further developed from the broadband mode to the ultra-wideband mode. Today, the bandwidth of many new radars has been developed to ultra-wideband mode. Therefore, the radar target echo simulator must realize the processing of UWB radar signals. As the core technology in the radar targe...
