| 摘 要： | 合成导向矢量最大似然算法对平坦阵地的米波雷达测高具有较高的精度,但在高山阵地下,会出现仰角空间谱模糊的现象,测高精度较低。鉴于此,本文提出了一种基于合成导向矢量最大似然算法的雷达变频测高方法,依据不同频点空间谱模糊的周期不同的特点,通过变频计算得到真实的目标仰角,仿真数据验证了该方法的有效性。

| Abstract: | The synthetic steering vector maximum likelihood algorithm has high accuracy for height finding of VHF radar at flat positions,but its height finding accuracy is degraded at high mountain positions due to elevation spatial spectrum ambiguity.In view of this problem,this paper proposes a multi-frequency radar height finding approach based on the synthetic steering vector maximum likelihood algorithm.Different frequency points have different characteristics of spatial spectrum ambiguity.Therefore,the true target elevation angle can be obtained through multi-frequency calculation.The simulation results prove the effectiveness of the proposed height finding approach. |
