针对低截获概率雷达设计了一种线性调频和相位编码混合信号，这种混合信号兼有线性调频和相位编码信号的优点，又弥补丁各自的缺点，以小时宽、小带宽获得大信噪比改善。文中对这种混合信号的性能及脉冲压缩处理进行了理论和仿真分析。

A compound signal composed of linear frequency modulation(LFM) and binary phase-coded(BC) signal for low probability intercept(LPI) radar is given in this paper. This compound signal has the advantages of LFM&BC and can make up their deficiency, The signal-noise ratio will be greatly improved by small time-width and frequency-width. Theoretical analysis and simulation for the characterstics, and pulse-compound process of the signal are given.
