Efficiency of Two-Stage Spectral Analysis for Noise Radar in the Presence of Clutter

摘要

Noise radars with two-stage spectral analysis of the received signals are considered. Analytic expressions are derived and examples of calculation are presented for the mean values of signals generated at the input and output of a single-fold interspan cancellation system and for the output signal-to-interference ratio attained in the presence of clutter and a slowly moving target that changes its range coordinate within the range bin during the time interval between two surveillance sessions. Values of the signal-to-interference ratio attained in the course of two-stage spectral analysis are compared with the corresponding values attained in the course of classical cross-correlation processing.
