摘要
角闪烁是雷达目标后向散射特性的重要物理量,它能严重降低毫米波末制导雷达的导引精度,影响雷达三维成像的质量。本文针对宽带毫米波雷达角跟踪中的角闪烁问题,研究了一种利用频率捷变技术获取目标回波信号的多个独立样本来抑制角闪烁的方法。仿真结果证实了该方法的有效性。
Angular glint is an important parameter of radar targets" back-scattering characteristics. It can seriously reduce the guidance accuracy of millimeter radars, and affect the quality of the 3-dimensional imaging of monopulse radars. For the glint occurring in angular tracking of wide-band millimeter radar, a method for glint suppression is introduced based on frequency agility. The simulation results indicate that the method is effective.
