基于红外导引头的制导信息提取算法

The Study of Information Reconstruction Based on the Guidance-information of Infrared Seeker

对红外制导空空导弹来言,许多制导信息如弹目相对距离、接近速度、目标加速度等无法直接测量,考虑红外导引头的测量特性,从制导信息重构的角度出发,研究如何利用导弹导引头及惯导等传感器的信息来精确的重构出几种先进制导律所需的制导信息,并将其引入到制导控制回路中,通过仿真验证了重构算法的正确性和实用性。

For infrared-guided air-to-air missile,a lot of guidance information such as the relative distance,approaching speed,and target acceleration cannot be directly measured. Considering the measurement characteristics of infrared seeker,it is mainly researched from the perspective of guidance information reconstruction that how to use the missile seeker and inertial sensor information to try to accurately reconstruct the guidance information of several advanced guidance law researched in the paper,and the simulation verified the correctness and the practicability of the reconstruction algorithm.
