| 摘 要： | 多输入多输出（MIM0）雷达是一种新体制的雷达，与双基地雷达相比，能够较好地对切向飞行目标进行检测。针对MIMO雷达的动目标显示（MTI）特性，给出了MTI滤波器的三种设计及其结构，并导出了其相应的改善因子表达式。最后给出了仿真结果，即递归滤波器具有较好的灵活性和改善因子，同时合理进行收发布阵，能够提高改善因子，这对MIMO雷达的布阵具有一定指导意义。

| Abstract: | As the new radar system, MIMO （multiple input multiple output） radar can detect vertical flight targets much better than bistatic radars, contraposing the characteristic of MTI （moving target indication） processing of MIMO radar, three kinds of designs structures of MTI filter are given, and three expressions of improvement factor are deduced. The simulation results show that the recursive filter has best flexibility and best improvement factor, and reasonable arrangement and receive array can meliorate the improvement factor. It has a certain significance to the distribution of MIMO radar. |
