Abstract
DRDC Ottawa has contracted C-CORE for software support services related to the analysis of pulse repetition frequencies (PRF) for distributed radars. Analysis and testing was performed using the Adaptive Multi-Function radar simulator (Adapt MFR) with particular interest in using target localization to resolve range ambiguity at higher PRFs. The main purpose of this work was to analyze PRF trade-offs for the resolution of range and Doppler ambiguities and to characterize target localization for distributed radars as well as analyze the effect of PRF on range and Doppler ambiguities for distributed radars. Several Adapt MFR simulations were performed using both single radars with different PRF values and multiple radars with a shared central tracker and coordinated radar resource management, which assigns tracks to specific radars. It was expected that the differing PRFs used in a multi-radar simulation would result in improved target detection and consequently track completeness due to greater target return power outside the unambiguous range and Doppler zones. However, no significant change in track completeness was observed. When performing track assignment to specific radars in coordinated RRM the tracker does not currently use knowledge of ambiguity zones and can assign tracks to the radar that has a PRF which positions the track in an ambiguity zone. This could result in a lost detection and lower track completeness. Through analysis and testing it has been determined th
