Radar sensor (RS) deployment for multi-target detection

Abstract

Radar sensor deployment is of great importance for radar sensor network (RSN) provisioning. A RSN is effectively deployed to detect multi-target within a given surveillance area with required detection performance and energy consumption. In this paper, we explore two deployment strategies-Hexagonal Deployment Strategy(HDS) and Diamond Deployment Strat-egy(DDS). We propose two decision fusion rules over pass-loss fading channel in multi-hop RSN to improve the performance of multi-target detection and appraise the DDS and HDS strategies. Each Radar Sensor(RS), separately, obtains probability of multitarget detection depending on the position of RS according to the deployment strategies. We combine these two decision fusion rules with random local detection probability. Performance evaluation shows that compared with random deployment strategy (RDS), the proposed two deployment strategies improve immensely the detection probability and are energy efficient. Using DDS to deploy a finite number of RSs with binary transmission (BT) to fuse data can achieve optimal probability of multi-target detection and consume least energy among the schemes in our paper.
