Abstract

Imaging in bistatic radar has been known a more difficult task than that in monostatic radar. It is because the behavior of the bistatic range and the bistatic Doppler due to the motion of a transmitter and a receiver is so random that the compensation procedure, which we call an imaging algorithm, is quite complicated. This paper presents a bistatic radar imaging algorithm that can be used in some specific bistatic radar geometry. We show this geometry can present rectangular-like resolution cell on isorange-isoDoppler contours map. We also present the associated resolution and simulation results.

바이스태틱 레이더 환경에서 지상 표적의 이미징은 수신 데이터 획득 시간 동안에 송신부 및 수신부의 이동에 따른 레인지 및 도플러 정보의 변화가 복잡하여 이에 대한 보상과정, 즉 이미징 과정이 모노스태틱 레이더 환경에 비해 상당히 어렵다. 본 논문에서는 아이소레인지(isorange)와 아이소도플러(isoDoppler) 컨투어 정보를 이용하여 이미징이 가능한 resolution 격자를 추출할 수 있는 바이스태틱 레이더 송수신기 geometry를 제시하고, 고정된 표적을 이미징할 수 있는 알고리즘을 제시한다. 또한, 이때 얻을 수 있는 해상도를 분석하고, 시뮬레이션으로 성능을 검증한다.
