基于回波调斜的密集假目标干扰对抗方法
Dense false-target jamming suppression method based on echo Frequency Modulation slope modulation
摘要
Abstract
Concealed dense false target jamming generates false targets with regular amplitude variations,increasing the radar's constant false alarm detection threshold and making it difficult to distinguish between real and false targets,posing a serious threat to radar systems.To this end,this paper proposes a counter-strategy against dense false target jamming based on echo Frequency Modulation(FM)slope modulation.The strategy first constructs a reference signal to tilt the echo pulse and then,based on the peak distribution characteristics of the matched filter output after tilting,designs two interference suppression methods for different scenarios:one is the sum and difference dual-path cancellation combined with time-domain filtering when the coherent pulse accumulation count is small;the other is direct coherent accumulation when the pulse accumulation count is large.Simulation results show that the proposed interference suppression methods are significantly effective in both modes.关键词
