However, compared with the traditional seeker using inertial platform, the line of sight(LOS) rate of strapdown seeker can not directly be measured. In addition, more measurement noise is induced due to the wide sighting field.
然而,与采用常平架式导引头的传统导弹相比,捷联导引头的视线角速率不能直接提取,大的视野范围也导致了大的测量噪声,针对这两个缺点,本文研究了捷联成像导引头的视线角速率的提取方法。
