摘要
双通道对消方法作为一种有效的SAR抗干扰方法,在进行SAR干扰抑制的同时,在部分周期性区域会产生导致目标损失现象。从理论上导出了目标损失周期的表达式,并分析了影响目标损失周期的参数,最后通过仿真验证了该表达式的正确性。
As an effective SAR anti-jamming method,two-channel cancellation results in the target losing at part period areas when it suppresses SAR jamming. The period expression of target losing is educed,and the parameters that affect target losing period are analyzed in the theory. Finally,the expression is verified correctly through simulation.
