Analysis of Measurement Association Methods in PCL-PET Passive Location System

The most comprehensive challenge in tracking system for PCL-PET (Passive Coherent Location – Passive Emitter Tracking) multistatic passive radiolocation system is the problem of ambiguity of measurement association to tracks due to different coordinate systems (bistatic and polar systems for measurements and Cartesian system for tracking). This paper analyzes measurement association methods in order to maximize the sum of gains of all associations and also analyzes multihypothesis measurement association method.
