摘　　要：连续波雷达具有结构简单、体积小、无距离盲区、低功耗和低截获、成本低等优点,在军用导航、战场侦察等领域得到广泛应用。文中对双频连续波、多频连续波、步进频率连续波和步进频移键控连续波等4种体制连续波雷达信号处理系统的参数设计和信号处理问题进行了对比分析,得到了各个波形的特点,并通过计算机仿真进行了验证。综合仿真结果和理论分析得到,步进频移键控连续波,能在一个处理周期内对多目标进行分辨。The CW radar has been widely used in military navigation,battlefield reconnaissance and other areas due to its advantages of simple structure,small volume,no distance blind,low cost,low power consumption and low probability of intercept. This paper is focused on the key problems of dual frequency CW radar,multiple frequency CW radar,stepped-frequency CW radar and stepped frequency shift keying CW radar,which are simulated to get the characteristics of each waveform. The results show that the stepped-frequency CW radar can solve the problem of multi-target identification within a treatment cycle.
