Target Detection and Tracking Simulation of Air Defense Radar in High-Density Clutter Environments Using a Real-time Simulator

Abstract

This paper proposes a target detection and tracking simulation algorithm for an air defense radar compatible with the real-time simulator of vsTasker. Searching spaces are divided based on practical radar specifications such as the radar antenna beam, pulse repetition time, and revolutions per minute. Time-series data of the position corresponding to the movement of the airborne target are generated. A detection error is randomly generated depending on the signal-to-noise ratio and in a high-density clutter environment; the distribution of reflected signals by the clutter is assumed to be a Weibull distribution. The simulated radar position of targets is processed using a LM-IPDA technique to generate the target track.
