Medium-PRF detection by non-coherent integration

The document describes a detection and inherent ambiguity resolution scheme for Medium-PRF waveforms. Medium-PRF waveforms are characterized by ambiguous measurements of both range and doppler. Ambiguities are resolved by changing the pulse repetition frequency (PRF) from burst to burst and by combining the ambiguous results of adjacent bursts. The classical binary integration procedure applies a detection threshold on burst level and combines detections from burst to burst including unfolding of the ambiguities. In this paper the more optimum method of non-coherent integration from burst to burst with inherent ambiguity resolution is discussed. The method provides a significantly improved detection performance. Of particular interest for non-coherent integration is the appearance of ghost targets. The paper proposes a method for deghosting.
