Abstract

Generally, bistatic clutter, contrary to the monostatic clutter, has nonlinear structure in Angle-Doppler domain due to the noncooperative motion of the transmitter and the receiver. In this paper, we first simulate the bistatic clutter structure resulting from the relative motion of the transmitter and the receiver and then analyze their relations through the bistatic clutter structure in Angle-Doppler domain. Also, we show the operation condition of the transmitter and the receiver leading to low rank of a covariance matrix of the bistatic clutter.

일반적으로 바이스태틱 클러터는 송신단과 수신단의 독립적인 이동에 의해 모노스태틱 클러터와는 달리 Angle-Doppler 평면에서 비선형적인 클러터 구조을 갖게 된다. 본 논문에서는 시뮬레이션 기법에 의해 Angle-Doppler 평면에서의 바이스태틱 클러터 구조를 이용해서 송신단과 수신단의 이동에 의한 클러터 구조 변화에 대해 분석한다. 또한, 시뮬레이션 결과를 통해 바이스태틱 레이더에서 클러터 공분산 행렬의 Rank가 가장 적게 되기 위한 송 수신단의 운용 조건을 보인다.
