针对双基地雷达的探测需要,文章研究了一种基于旋转不变子空间(ESPRIT:Estimation of signal parameters via rot-ational invariance techniques)的信号发射角(DOD:Direction of Departure)和信号接收角(DOA:Direction of Arrival)估计方法.该方法使用多输入多输出(MIMO:Multiple Input Multiple Output)阵列,利用发射和接收阵列的不变特性,分别估计出感兴趣目标的DOD和DOA,同时进行目标的收发角度配对.文章将该方法应用到MIMO阵列中,并通过计算机仿真验证了其有效性.

For the requirement of bistatic detecting radar, this paper discusses the Direction of Departure (DOD) and Direction of Arrival (DOA) estimation method based on Estimation of signal parameters via rotational invariance techniques(ESPRIT). This method makes use of multiple input multiple output(MIMO)array, exploits the invariance of emitting and receiving array, independently estimates the DOD and DOA of target of interested, then achieves the pairing of emitting and receiving angles. This paper adopts ESPRIT to MIMO array, and computer simulation demonstrates the efficiency of the method.
