摘　　要：以“红土地”国产化导引头为例,详细介绍了动力陀螺式激光导引头的结构组成、工作流程和跟踪原理,并阐述了激光导引头数学模型及建模过程。针对其动力陀螺稳定平台特性,研究了其在火箭弹、空地导弹、航空炸弹等平台的应用。针对采用倾斜稳定三通道控制的非旋转弹提出的导引头输出斜率补偿算法,可有效降低导引头输出斜率散布;针对采用双通道控制的旋转弹提出的导引头转速自适应算法,在弹体转速0~10 r/s范围内实现了动力陀螺稳定平台式激光导引头的自适应工作。斜率补偿和转速自适应两种算法均已通过仿真试验考核以及地面联试与飞行试验验证,实现了工程应用。"Red Earth"domestic seeker is taken as an example,and the structure,work flow and tracking principle of the dynamic gyro laser seeker are introduced in detail.The mathematical model and modeling process of the laser seeker are described,and its application in rocket,ground missile,aviation bomb and other platforms is studied according to the characteristics of its dynamic gyro-stabilized platform.For the non-rotating missile controlled by tilting stable three-channel,the dispersion of seeker output slope can be effectively reduced by the seeker output slope compensation algorithm.For the rotating missile with dual-channel control,the seeker speed adaptive algorithm is proposed to realize the adaptive operation of the dynamic gyrostabilized platform laser seeker when the body speed is in the range of 0-10 r/s.The two algorithms have passed the simulation test and completed the engineering application after ground joint test and flight test.
