摘要
角闪烁是雷达目标特征的重要方面,它能严重降低近距离反导雷达的测角精度。文中利用了雷达散射截面和角闪烁之间的相关性抑制角闪烁的加权方法,为实现这一方法,采用了空间分集技术来获取目标回波信号的2个或多个独立样本。仿真结果表明,即使2个天线的处理,角闪烁线偏差的均方根从3 m降低至1 m。
Angular glint is an important parameter of radar target characteristics. It seriously reduces angle tracking accuracy of close in antimissile radar. In this paper, the weighting theory that can suppress the angular glint by utilizing the cross correlation between RCS and angular glint is discussed. To accomplish this RCS weighting method, space diversity is employed to get inde- pendent samples of target echo signal. The simulation result shows that the square root error value of glint can be suppressed from 3m to about lm using two antennas.
