Radar detection during tracking with constant track false alarm rate

In traditional radar systems, target detection and target tracking are conducted separately, but if they are considered as a whole, higher target detection and tracking performance may be obtained. In this paper, we study how to perform target detection during target tracking. At the target tracking stage, we use the knowledge provided by the target tracking algorithm to facilitate target detection, and propose a criterion that a target track can terminate at a given probability when the target reflects no signal back suddenly. Simulation results indicate that this method can significantly improve the detection probability and expand the tracking distance at a low level of track false alarm rate.
