Target tracking via multi-static Doppler shifts

This article studies the problem of joint detection and tracking of a target using multi-static Doppler-only measurements. The assumption is that in the surveillance volume of interest a single transmitter of known frequency is active with multiple spatially distributed receivers collecting and reporting Doppler-shift frequencies to the data fusion centre. The measurements are not only affected by additive noise but also contaminated by false detections and missed detections. The study develops for this application of a multi-sensor Bernoulli particle filter with information gain-driven receiver selection. The simulation results indicate robust performance of the proposed Bernoulli particle filter.
