| 摘 要： | 针对杂波回波对连续波雷达探测性能的影响,介绍了动目标显示(Moving Target Indication,MTI)的基本原理,提出了MTI在伪码调相连续波雷达中的实现方法,详细对比分析了该方法对高速目标与低速目标的不同影响及不同多间隔周期对MTI处理性能的影响。该方法可实现对杂波的抑制,明显改善伪码调相连续波雷达在杂波区域的性能,同时可减少对低速目标的损耗,计算机仿真结果表明MTI在连续波雷达中具有较大的应用价值。 |

| Abstract: | In order to reduce the effect of clutter echo on detection performance of CW radar,the basic principle of MTI is introduced and an implementation method for MTI in pseudo-random code phase modulation continuous wave（PRCPM-CW） radar is proposed.The different effects of the method on high velocity target and low velocity target and the effect of different multiple interval cycles on the processing performance of MTI are compared and analyzed in detail.Through the method,the clutter is suppressed,the performance of PRCPM-CW radar in clutter region is improved,and the loss of low velocity target is decreased.Simulation results show that MTI has great application value in CW radar. |
