摘　　要：基于线性调频连续波及圆锥扫描理论,研究锥扫线性调频连续波雷达信号处理方法.针对回波信号的特点,将频域法运用于锥扫线性调频连续波信号.论证了该信号可以在距离高分辨率的基础上进行有效测角,分析了信号处理时频谱泄漏对系统造成的影响,并对泄漏进行了补偿.计算机仿真结果表明,该方法可应用于跟踪雷达的信号处理中.Based on the theory of liner frequency modulated continuous wave （LFMCW） and conical scan, the signal processing methods of conical scan LFMCW radar are analyzed. According to the characteristics of the echo, frequency domain method（FDM） is used on the conical scan LFMCW to achieve the expression which can obtain angular information as well as high range resolution image. Effects of spectrum leakage to the system are also analyzed, and the compensation of leakage given. Simulation results showed that these methods can be used in tracking radar.
