Moving Multitarget Detection Using a Multisite Radar System with Widely Separated Stations

This study investigates the detection problem of multiple moving targets using a multisite radar system with widely separated stations. Spatial mapping is presented to integrate observation data target from different angles into spatial resolution cell (SRC). However, association errors occur in some SRCs this way, which causes extra false alarm, called “ghost target”. Therefore, an interference discriminator-based detector developed. In background discriminated between target” and pure noise, then final decision made based on generalized likelihood ratio test. Statistical analyses are provided discuss achievable performance. Simulation results show that proposed algorithm can accurately detect while suppressing
