摘要
本文从星载SAR(SyntheticApertureRadar)的应答式欺骗干扰方法入手,在研究应答欺骗式干扰原理的基础上,建立了SAR地面目标回波模型。通过分析回波多普勒频移和调频速率,计算出应答干扰机所需的合成假目标数据,从而得到了相应的干扰信号。
This paper introduces a method of the responsive deception for spaceborne SAR. Based on the principle of the responsive deception, the authors construct a mathematical model of echo signals from ground objects. The paper works out the false object's data that a device of deception demands and evaluates corresponding signals of deception by analyzing Doppler frequency and rate of frequency modulation.
