摘　　要：调频连续波(FMCW)雷达的隔离度影响雷达探测距离。分析了在不同距离条件下对FMCW雷达发射机和接收机的隔离度要求,采用相控阵天线提出了一种基于凸优化的隔离度改善方法,该算法通过零点技术来抑制发射机耦合到接收机的信号。仿真实验验证了所提算法的有效性。The isolation of frequency modulated continuous wave （FMCW） radar affects the radar detection range. This paper analyzes the isolation requirement to the transmitter and receiver of FMCW radar under conditions of different detection ranges, presents an isolation improvement method based on convex optimization （IIM CVX） by using the phased array antenna,which is able to suppress the leakage from the transmitter into the receiver by the notch technique.The simula tion experiment verifies the effectiveness of the proposed technique.
