Zusammenfassung:	A radar performance evaluation system and a radar performance evaluation method for evaluating radar performance are disclosed. The radar performance evaluation system according to one embodiment comprises: a processor that models an array antenna and mounting structure of a radar, simulates mounting performance of the mounting structure based on the modeled array antenna and mounting structure, analyzes an amplitude and phase of antenna reception current for each signal direction based on the simulation, determines distortion of reception performance based on the analyzed amplitude and phase, derives a radiation pattern of the array antenna, determines distortion of the radiation pattern based on the derived radiation pattern, and generates antenna relocation information for relocating the array antenna based on the distortion of reception performance and distortion of the radiation pattern; and a storage unit that stores the amplitude and phase of antenna reception current, the derived radiation pattern and the antenna relocation information. The radar performance evaluation system evaluates radar performance based on complex reception current applied to the array antenna of the radar. 레이더의 성능을 평가하는 레이더 성능 평가 시스템 및 레이더 성능 평가 방법이 개시될 수 있다. 일 실시예에 따른 레이더 성능 평가 시스템은 레이더의 배열 안테나 및 탑재 구조체를 모델링하고, 모델링된 배열 안테나 및 탑재 구조체에 기초하여, 탑재 구조체의 탑재 성능을 시뮬레이션하고, 시뮬레이션에 기초하여 신호 방향별 안테나 수신 전류의 진폭 및 위상을 분석하고, 분석된 진폭 및 위상에 기초하여 수신 성능의 왜곡을 결정하고, 배열 안테나의 방사 패턴을 도출하고, 도출된 방사 패턴에 기초하여 방사 패턴의 왜곡을 결정하고, 수신 성능의 왜곡 및 방사 패턴의 왜곡에 기초하여 배열 안테나를 재배치시키기 위한 안테나 재배치 정보를 생성하는 프로세서; 및 안테나 수신 전류의 진폭 및 위상, 도출된 방사 패턴 및 안테나 재배치 정보를 저장하는 저장부를 포함할 수 있다.
