摘　　要：首先介绍了几种UHF波段雷达的情况,然后针对目前应用在反辐射导弹上的测向方法难以满足对UHF波段的辐射源准确测向的问题,以及相位干涉仪测向体制的导引头的命中精度进行了理论分析,继而提出了利用空间谱估计理论在较小的天线安装体积内实现此波段的准确测向,给出了辐射源入射的数学模型、MUSIC算法的基本步骤及天线的阵列形式。仿真结果表明应用此方法可满足反辐射导弹的测向精度要求。使用新测向体制的反辐射导弹攻击UHF波段雷达会有更好的效果。The main performance of ultra high frequency（UHF） radar is presented at first and the UHF radiant source direction finding precision problem of the methods now using in the anti-radiation-missile（ARM） is analyzed, as well as the shoot precision of the phase interferometer guider is analyzed. The method of using special spectral estimation is proposed to realize high precision direction finding in less antenna array volume, the mathematical model of radiant sources, basic steps of MUSIC algorithm and antenna array form are presented. Simulation results show that this method can satisfy the direction finding precision need of ARM. Using new direction finding system in ARM that attacks UHF radar must have better effect.
