Abstract
In order to improve the fast positioning and anti-jamming locking ability of low-frequency phased array radar to air targets,a fast positioning algorithm for radar departments anti-sidelobe interference based on range sidelobe beam suppression of shared signals and frequency domain matched filtering is proposed,and a radar communication shared signal model is constructed,and the power spectrum of transmitted signals is adaptively weighted according to the modulation data of signal subcarriers at different positions.The sidelobe signal beam suppression of low frequency phased array radar signal is realized by frequency domain matched filtering and amplitude weighting processing,and the signal interference superposition is realized by combining the amplitude,phase and time delay parameters between transmitting elements,and the target azimuth estimation and positioning are realized by autocorrelation beamforming.The simulation results show that the algorithm can estimate the signal parameters of low-frequency phased array radar,effectively locate the control target,and has good anti-jamming ability and adaptive parameter estimation ability,which improves the operational parameter performance of air defense radar.关键词
