基于目标RCS加权滤波方法抑制角闪烁的研究

Research on Suppressing Glint by Target's RCS Filtering

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。

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.
