摘要
针对激光半主动式制导炸弹导引信号形成过程的数学建模,通过对风标式激光导引头光学物理结构分析,本文研究了激光导引头制导信号产生的机理,提出光电建模与几何分析相结合的技术途径,综合应用四象限探测器光电建模和弹目空间与速度空间几何角度转换的方法,建立了速度追踪导引机制下完整的导引头数学模型;基于模型进行了激光半主动式制导炸弹导引回路数学仿真和半实物仿真实验。实验结果表明,在排除盲区、失调角影响因素外,数学仿真中应用导引头数学模型解算的导引信号与半实物仿真中激光导引头的实际输出信号一致,导引头数学模型是有效的,解决了激光导引头仿真中由定性研究转为定量研究问题。
Through the analysis of the optical physical structure of aerodynamically stabilized seekers, the laser guided signal mechanism was studied in this paper for the completion of the seeker signal mathematical modeling of the semi-active laser guided bombs in the guided process, and the technical combination approach for lector-optic modeling combined with geometric analysis was proposed. The methods of electro-optic modeling on four-quadrant laser detector and coordinate system transition between the line-of-sight space and the velocity space were applied to build up the complete mathematical model of the velocity tracking seeker. Based on the mathematical model, the guided loop simulation experiments were carried out in the mode of mathematical simulation and hardware in-the-loop （HWIL） simulation. The experimental results show that the calculated signal in the mathematical simulation is consistent with the actual output signal of the laser seeker in the HWIL simulation under the condition of eliminating the effects of the dead zone and the misalignment angle. The mathematical model is valid, which resolves the problem of laser seeker simulation from qualitative research to quantitative research.
