双机频率域交替闪烁的协同相参信号处理方法
Cooperation Coherent Signal Processing Method for Alternating Flicker in the Frequency Domain of Dual-aircraft
摘要
Abstract
Multi aircraft cooperative detection expands the complexity of radar radiation waveform from the aspect of airspace,and provides more possibilities for air combat field strength against covert detection in complex electromagnetic environment.In this paper,the working mode of two aircraft self transmit and receive signal level cooperative detection is designed,and a phase error estimation and sparse scene reconstruction method based on the combination of multiple underdetermined system solver(MFOCUSS)and alternating direction multiplier method(ADMM)is proposed.Simulation results show that this method can accurately estimate the system phase error and effectively coherently accumulate and reconstruct the scene of two frequencies at any interval.Through the research,a new dual-aircraft cooperative detection mode has been designed,which solves the phase correction and scene reconstruction issues in the dual-aircraft frequency flicker detection mode.This provides a signal processing method for cooperative detection under complex electromagnetic environments.关键词
