Abstract

Abstract:

The reduction of the signal bandwidth and sampling frequency is conducive to the realization of antenna array thinness based on the micro system so as to improve the adaptability of the large aperture antenna on the ultra-high speed platform.However,the high-resolution range profile of the ground moving target is required for accurate tracking and recognition of the ground moving target.In order to solve this problem,a system architecture and processing method based on the low instantaneous bandwidth digital array of transceiver reciprocity is proposed,which can realize high resolution ground moving target display(GMTI) by frequency band synthesis.Because the array transceiver reciprocity can realize the coincidence of the equivalent phase center,the phase difference of the target deviated from the beam center does not need to be compensated in the process of bandwidth synthesis,and the precise synthesis of large bandwidth signals can be realized.After the synthesis of the wideband signal,the clutter is suppressed by space-time adaptive processing(STAP) to realize the detection of ground moving targets.Simulation results verify the correctness of the system architecture and processing method.

Key words: moving ground targets, frequency band synthesis, system architecture, transceiver reciprocity, adaptive processing
