DISTURBING SIGNAL CANCELLING METHOD AND APPARATUS

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: $The\; target\; return\; signals\; E/m\; processed\; in\; the\; main\; channel\; are\; then\; determined\; in\; accordance\; with\; the\; equation:\; E\; min\; m\; =\; Em\; -\; W1E1\; -\; W2E2-\; .\; .\; .-WnEn.$
