Deception jammer rejection using pulse diversity in joint slow/fast-time domain

摘要

In this article, a method based on the theory of pulse diversity is presented for rejecting a deception jammer which is repeated by a digital radio frequency memory. The application conditions involved in slow-time approach, which cancels the jammer across several pulse repetition intervals, is restricted to the hypothesis that the reflectors and reflectivity levels remain stationary making it impractical in rapidly varying conditions. This issue is resolved through producing new vectors from the original transmission signals in joint slow/fast-time domain. Moreover, the presented method also insures satisfactory performance levels when the target and jamming pulses are overlapped.
