Elimination in a pulse radar receiver of interference signals stemming from N distinct sources

摘要

In a method for the cancellation of interference signals, originating from a number n of sources, a radar receiver containing a main channel and a number n of auxiliary channels for the reception, i.f. detection, sampling and digitising of signals Em E1, E2 . . . , En, is used, which signals are composed of target return signals and interference signals. From these signals weighting factors W1, W2, . . . Wn are obtained in accordance with the matrix equation: MATH The target return signals E/m processed in the main channel are then determined in accordance with the equation: E min m = Em - W1E1 - W2E2- . . .-WnEn.
