| 摘 要： | 为了进一步改善战场侦察雷达对杂波的抑制能力,通过对递归与非递归动目标显示(MTI)滤波器的性能研究,总结了零级点对MTI滤波器性能的影响。结合战场侦察雷达的特性,设计了3种MTI滤波器模型。通过仿真分析其频谱特性和改善因子,结果表明,在不同的杂波背景下,选择设计相应的MTI滤波器,能够有效抑制杂波,并能得到较大的改善因子。

| Abstract: | In order to improve the suppression capability of battlefield surveillance radar on clutter,the influence of pole-zero on Moving Target Indication(MTI) filter is summarized by researching the performances of recursive MTI filter and nonrecursive MTI filter.Combining characteristics of battlefield surveillance radar,three different MTI filter models are designed.After analyzing the spectral characteristics and improvement factors by simulation,it is indicated that under different clutter circumstances,selecting and designing a corresponding MTI filter may effectively suppress clutter and get better improvement factors. |
