Paper Abstract

Passive Coherent Location (PCL) is a low-cost system for tracking of air targets clandestinely using illuminators of opportunity such as FM broadcast and digital TV. Due to an increased interest in PCL systems, researchers have been working on different configurations of available sources of opportunity and receivers capable of extracting plots from reflected signals of opportunity. The configuration can be multiple-transmitter-single-receiver or singletransmitter- multiple-receiver. Unlike standard radar systems, which can be optimized for detection probability and/or false alarm rate using different transmitted signals and adaptive thresholding, PCL systems are prone to poor detection due to low signal-to-noise (SNR). This leads to high clutter with low probability of detection of target of interest. In this work, we implement a multisensor-multitarget tracking system that fuses measurements from different PCL systems to improve tracking results. The benefits of the fusion are demonstrated using real data from NATA SET Panel 108 on PCL as well as simulated data.
