结合近程制导火箭特点,研究了捷联寻的制导关键技术,如捷联导引头信息处理、捷联寻的与制导控制一体化设计、导引规律设计等。基于某在研近程制导火箭的数学模型,采用UKF滤波器提取视线角速率,提出了制导控制一体化设计思路,采用蒙特卡罗法分析了低成本捷联寻的制导技术应用的可行性。仿真结果表明,制导精度满足设计要求。

Based on the characteristic of short-range guided rocket, the key technologies of strapdown homing guidance technology such as strapdown seeker information processing, integrated design of guidance and control system, guidance law design, etc. were researched. The feasibility of this technology in short-range guidance rocket, including LOS estimation by UKF, integrated design method of guidance and control system, hit precision were analyzed and simulated by Monte Carlo method. The results show that the guidance precision meets the design requirement.
