Abstract :
Track-Before-Detect has been shown to offer significant sensitivity improvements over point-measurement tracking. However, it uses the whole sensor intensity map as a measurement and it can be infeasible to communicate these maps around a distributed network. This paper investigates the degradation in detection and estimation performance when lossy compression is used to limit communication bandwidth.
