本文将该方法推广到

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.

Abstract

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

-channel cancellation processing

which allows the method to be applicable

effective

and theoretically complete.
