摘要
针对合成孔径雷达(SAR)压制性干扰的抑制问题,提出了一种三通道对消方法.首先从理论上给出了该方法抑制压制性干扰的原理及对SAR成像产生的影响,然后导出了目标回波信号的损失周期表达式,最后进行了仿真实验.与双通道对消处理的比较结果表明,本文所提出方法在SAR抗干扰方面具有的优越性.此外,本文将该方法推广到N通道对消处理的一般意义情况,从而使该法抑制SAR干扰方法在应用上具有可行性和有效性,且在理论上具有完备性.
Aimed at the SAR blanketing jamming suppression, a method of three-channel cancellation is proposed. First,principles of the method to suppress blanketing jamming and its influences on SAR imaging are presented in theory, from which the expression of target loss period （TLP） is derived,and then the simulation experiment is carried out. The results show the superiority of the proposed method for SAR anti-jamming in comparison with the method of two-channel cancellation.In addition, this method can be extended to the general circumstance of N-channel cancellation processing, which allows the method to be applicable,effective, and theoretically complete.
