Abstract
논문에서는 레이더 시스템에서 코히런트 집적과 비 코히런트 집적의 SNR 성능에 대해서 비교한다. 본 논문에서는 레이더 시스템에서 반사파와 전송파의 왜곡을 방지하기 위해 펄스파를 송신 파형으로 사용하였다. 본 논문에서는 포락선 검파기 앞에서 처리하는 코히런트 집적과 포락선 검파기 뒤에서 처리하는 비 코히런트 집적을 사용하여 목표물 탐지 거리를 추정하고 집적 방식에 따른 SNR 성능을 비교한다. 모의실험을 통해서 코히런트 집적과 비 코히런트 집적의 SNR 성능을 비교 분석하였다. 코히런트 집적이 비 코히런트 집적보다 SNR 성능이 우수함을 입증하였다. This paper compare with SNR performance of coherent integration and non-coherent integration in radar system. This paper to prevent distortion of transmit signal and radar return in radar system is used to pulsed waveform. This paper to estimate target detection range and to compare with SNR performance used to coherent integration performed before the envelope detector and non-coherent integration processed after the envelope detector. Through simulation, SNR performance of coherent integration and non-coherent integration were comparatively analyzed. SNR performance of coherent integration is good proof higher than non-coherent integration.
