A concept of multi-rate processing for passive radar

Abstract

In the paper the concept of a passive radar that uses several processing chains working with different setup parameters is considered. In the presented concept, the same signals are divided into blocks of different lengths, and processed simultaneously. In such way higher signal-to-noise ratios can be achieved for non-maneuvering targets by using longer integration time, whereas highly maneuvering targets can still be detected using shorter integration time.
