| 摘 要： | 单脉冲雷达进入末段跟踪状态后,其测角误差主要来自于目标的角闪烁。利用目标(RCS)起伏与角闪烁线偏差绝对值之间的负相关性,采用目标RCS加权滤波的方法能够有效抑制角闪烁。仿真数据和实测数据的验证结果表明,该方法能够有效抑制单脉冲雷达角闪烁现象,具有较高的工程应用价值。

| Abstract: | When the monopulse radar comes into the end segment of tracking,the angle measurement error mainly comes from glint.Using the negative relativity between the target’s radar cross section(RCS) and the absolute value of glint linear warp,the target’s RCS filter can suppress glint efficiently.The validation of simulation and practically measured data proves that this way can efficiently suppress glint and has high value for engineering. |
