摘　　要：为满足单兵拦截低空慢速小型无人飞行器实战中对弹道解算器的低成本、小体积、高精度的要求,设计了一种在STM32硬件平台上实现的手持弹道解算器。通过研究弹丸质心运动模型及其数值解法,提出并设计了基于STM32F407平台的提前命中目标位置的精确弹道解算方法,并完成软硬件调试。实验结果表明,设计的手持弹道解算器在精度和实时性方面能够满足单兵拦截低慢小目标作战需求。In order to meet the requirement of the single pawn to intercept the low-altitude, slow-speed and small-size UAV in the actual combat for the low-cost, small-size and high-precision trajectory solver, a handheld trajectory solver implemented on the STM32-based hardware platform was designed. The motion model of the projectile barycenter and its numerical solution are studied to propose and design the STM32F407 platform based accurate trajectory solving method to hit the target beforehand. The hardware and software are debugged. The experimental results show that the handheld trajectory solver can meet the fight re- quirement that the single pawn can intercept the low-altitude, slow-speed and small-size UAV in the aspects of the accuracy and real-time performance.
