弹丸在侵彻过程中,侵彻弹药上的高g值加速度计在获得有效的减加速度信号的同时,也会收到很多干扰信号,从而影响到准确的控制炸点。文中针对侵彻过程中加速度计接收到的双峰干扰,采用定时器延时控制的原理,提出了消除双峰干扰的方法并进行仿真,以保证精确的炸点控制。仿真验证表明,系统抗干扰性较好,能够精确判断层数。

In the process of projectile penetration, the high-g accelerometer in the penetration ammunition receives valid signal, it also receives a lot of interference signals, interference signal affects accurate control of burst point. For the bimodal interference in the penetration process, a method was proposed for eliminating bimodal interference by timer delay control principle and simulation. In order to guarantee accurately burst point, verified by simulation, the system is better for anti-jamming and layer-identify.
