- W2042956550 abstract "레이더는 표적으로부터 반사된 신호의 크기, 도플러 속도로부터 표적의 거리, 속도 정보를 알 수 있으며, 이런 반사 신호의 특징들은 표적의 반사 특성과 기동에 의해 결정된다. 표적의 위치 정보에 대한 각도 오차는 합채널에 대한 차채널의 크기 비로부터 추출된다. 본 논문에서는 다기능 레이더의 성능을 평가하고 분석하기 위한 레이더 반사 신호 모의 장치(RSSE)에 대해 소개하였다. 개발된 레이더 반사 신호 모의 장치는 다채널 직접 디지털 합성(MC-DDS)을 이용하여, 재밍 신호를 포함한 다중 표적 환경을 모사할 수 있도록 구현되었으며, 효율적인 하드웨어 구조 설계를 통해 모사할 수 있는 표적의 수를 용이하게 확장할 수 있도록 설계되었다. 개발된 모의 장치의 요구 성능 및 기능을 시험 환경에서 확인하였으며, 신호 처리기(RSP)와의 연동 시험 구성에서 표적 탐지 성능을 입증하였다. Radar receiving echo signal provides target information - range, velocity and position by signal magnitude and Doppler shift, which are determined by target reflection characteristics and target maneuver. Target angle error is extracted from the magnitude ratio of difference channel to sum channel. In this paper, we introduce a radar Return Signal Simulation Equipment(RSSE) which is implemented for the purpose of performance analysis and evaluation of phased array multi-function radar(MFR). It generates multi-target environment with jamming signals using MC-DDS (Multi-Channel Direct Digital Synthesis), and has scalability by using the efficient hardware configuration. The performance of the developed RSSE has been evaluated under various test environments. Especially, we proved that required target detection performance is achieved by RSP(Radar Signal Processor) interfaced RSSE configuration." @default.
