被动单脉冲导引头干扰源角度分辨

Angular resolution of jammers of the passive monopulse seeker

讨论了被动单脉冲导引头对窄带高斯噪声干扰源的角度分辨.在导引头主波束内只有一个干扰源情况下,导引头给出的平均到达角指向干扰源真实到达角方向.在导引头主波束内同时存在两个相互独立干扰源情况下,通过平均到达角理论分析和计算机仿真,导引头给出的平均到达角指向两干扰源功率重心方向.利用复角技术,可判断导引头主波束内是单目标还是多目标.并提出一种利用复角技术和聚类分析相结合的两干扰源角度分辨方法,计算机仿真证实了方法的有效性和正确性.

The angle resolving method of two narrow band Gaussian noise jammers for the passive monopulse seeker is presented. In the case of one jammer within the main beam, the average angle of arrival given by the seeker points in the direction of the jammer. In the case of two jamers within the main beam, the average angle of arrival points at the power centroid. One or two jammers within the main beam can be distinguished by the complex angle. By using the complex angle and clustering analysis, an angle resolving method of two jammers is presented. The method is verified with the results of digital computer simulation.
