摘　　要：针对迫弹平台导引头探测信号受弯曲弹道特性影响无法直接使用,结合迫弹典型的弯曲弹道特性,对捷联式激光导引头在弹道末端修正段的探测光斑变化规律进行分析研究,提出了基于激光光斑变化规律的制导控制方案,通过蒙特卡洛打靶法,对修正结果进行了仿真分析,仿真结果表明,将导引头光斑变化规律运用至制导律中,可有利提高弹药的修正精度。Aiming at that the probe signal of forced projectile platform can’t be directly used due to the influence of ballistic characteristics of bending, combining with typical ballistic characteristics of forced projectile, the change rule of detection spot of strapdown laser seeker in the correction section of ballistic end was analyzed and studied. A guidance control scheme based on the change law of laser spot was proposed, and the modified results were simulated by Monte Carlo shooting method. The simulation results show that applying the change rule of the seeker spot to the guidance law can improve the correction accuracy of the ammunition.
