基于单基地雷达组网的协同对消抗干扰反隐身方法

Anti-stealth method based on cooperative cancellation and anti-jamming of monostatic radar networking

为了弥补常规雷达组网数据级融合在主瓣干扰下的探测能力不足,提出了一种基于单基地雷达组网的协同对消抗干扰反隐身方法.该方法利用组网后目标和干扰的幅度、相位、延时和多普勒频移中的一种差异进行干扰对消.仿真结果表明,采用单基地雷达组网协同对消抗干扰方法主瓣干扰对消比约为25 dB,大大提升了复杂环境下的隐身目标探测能力.

In order to make up for the deficiency of detection ability of conventional radar networking data level fusion under the main lobe interference,this paper proposes an anti-stealth method based on cooperative can-cellation and anti-jamming of monostatic radar networking.This method uses the difference in amplitude,phase,delay and Doppler shift of the target and the interference after networking to cancel the jamming.The simulation results show that the main lobe jamming cancellation ratio is about 25 dB by using the method based on coopera-tive cancellation and anti-jamming of monostatic radar networking,which greatly improves the detection ability of stealthy targets in complex environments.
