| 摘 要： | 依据拦截弹与机动目标间的相对位置关系，采用导引头球面模型，基于当前统计模型，实现了强跟踪状态自适应滤波，计算出了可用于制导的视线角速率。该算法利用导引头球面模型，将测角信息转换成距离信息，进行方差自适应调整和卡尔曼滤波。在只给出视线角序列信息的情况下，根据相对状态滤波结果求出所需的视线角速率。

| Abstract: | According to the relative position between the interceptor and the maneuvering target,using seeker spherical surface model,the paper gives out the line-of-sight (LOS) rate for guidance through strong tracking adaptive estimation based on current statistics model.Associated with seeker spherical surface model and covariance adaptive adjusts,Kalman filter is developed with relative position information transformed from LOS angle information.When information of LOS angle sequence is merely provided,the approach can give LOS rate with relatively high precision. |

| Keywords: | current statistics model self-adaptive strong tracking line-of-sight rate Kalman filter |
