Abstract

This paper examines the detection of weak moving targets using long-dwell, multi-channel radar. The impact of unknown target motion on detection performance is addressed. Signal-to-noise ratio (SNR) loss caused by mismatch between the matched filter and the actual target phase history - as might occur when using conventional space-time adaptive processing (STAP) - is quantified, and major factors contributing to this loss are identified. Limits on dwell time and target motion are established for conventional STAP. Results in this paper form a basis for long-dwell algorithm development.
