为实现弹丸落/着点的非接触测量,针对训练中弹丸立靶密集度和首发命中率人工测量的现状,提出利用磁阻传感器感知弹丸经过时磁场强度和方向的变化。分析了该方法的基本工作原理,研究寻找磁阻变化和弹丸位置对应关系规律。同时对实施测量的定位系统基本结构进行初步探讨,为测试方法完善和测试设备的研制奠定理论基础。

Aiming at the status about vertical target precision of projectile and the hitting accuracy of the first round artificially measured, the magnetic resistance sensor was referred to be used to perceive the change of strength and orientation from the magnetic field during projectile passing. In order to realize non-contact measurement about the fall/impact point of the projectile, the law of correspondence relations between the change of magnetic resistance and poison of the projectile was researched and found, and the result of preliminary study of the fundamental structure of the positioning system, which is based on the embedded analysis of the operational principle of this test, will be shown to lay the foundation to improve the ways and means of the base test and develop testing equipment.
