Positioning Performance Evaluation for Passive Radar Network and Experimental Verification

Detection performance of Passive Radar Network (PRN) is affected by many factors including network geometry, radio propagation environment, performance of system, signal and data processing capability, and so on. Optimized disposition with passive radar network needs to consider all the aspects, and performance evaluation of the network should be firstly taken into consideration. Launching from the positioning performance of passive radar network, first a feasible evaluation scheme is proposed, and the distribution of positioning precision is obtained by Monte-Carlo simulation under a specified network configuration. Then, the experimental scenario and the experimental progress is highlighted, involving system introduction, illustration, and analysis of typical detection results of airplanes. Finally, the positioning accuracy is compared with reference information and simulation results, which proves the validity of passive radar network positioning performance evaluation scheme.
