Chaff centroid jamming makes the indicated angle of a target by a radar seeker bias off the target, which is catastrophic to the radar seeker target tracking. In this study, the authors propose to suppress the chaff centroid jamming by polarisation oblique projection without prior knowledge of the target and the jamming polarisation parameters. At first, they prove that interference-to-signal ratio...
The objective of this paper is to build some typical jamming models, to evaluate the performance of different jamming modes, and finally to develop a simulation system of SAR countermeasures. For this purpose, the mathematic models of various SAR jamming modes are analyzed firstly; secondly the whole image processing from raw data simulation to jamming mode choosing are carried out, where the optimal...
