Performance Bounds and Algorithms for Tracking with a Radar Array

Target tracking using a radar array system is considered. A signal model which includes the effects of path loss, signal delay, Doppler shift and angle-of-arrival is adopted. The conventional approach to radar tracking assumes that the raw measurements are processed to produce a collection of candidate target detections. We propose a new approach in which the raw received measurements are used for tracking. Performance bounds and a simulation analysis of filters developed for each model demonstrate the performance gains which can be achieved by tracking with raw sensor measurements.
