Passive detection and tracking of maneuvering targets with particle filter techniques using DVBT broadcasting

We present a complete and practical particle filter-based scheme to detect, classify and track multiple maneuvering targets using DVBT-based passive radar. As in the conventional radar signal processing, the proposed technique first detects the target Doppler and bi-static range considering the outputs of long-term correlation matched filters whose level exceeds an adaptive threshold. The detections are then followed by a bank of particle based-filters. Each filter tracks a detected target and estimates its position and velocity from the analysis of short-term correlations.
