Abstract
In radar operat양한 외부 원인에 의해 탐지 성능이 저하될 수 있다. 저하 원인으로는 대기 및 지형에 의한 손실뿐만 아니라, 간섭, 타 표적 등이 있다. 국내 운용 중인 레이ions, the detection performance is reduced owing to various external factors. These factors include interference and other targets, as well as losses from the atmosphere and terrain. Because of its geomorphic characteristics, radar operating in Korea is affected by interference, and its performance is degraded. This paper describes the simulation of the environment of near-radar interference and multiple targets. The modeling and simulation (M&S) tool was developed to predict and prevent the degradation in radar performance in advance. We validated existing constant false alarm rate (CFAR) detection algorithms by generating signals through the M&S tool and proposed a new CFAR algorithm to enhance the radar performance. Consequently, radar performance is enhanced by the new CFAR algorithm in radar interference and multiple target environments.
