| 摘 要： | 在野外复杂训练环境下,利用激波原理进行实弹射击的精度坐标报靶,是一项具有相当挑战性的技术.本文采用FPGA (Field Programmable Gate Array,现场可编程门阵列)结合自适应滤波技术,对报靶系统采集的激波信号进行了实时滤波处理.采用VHDL语言编程,利用QUARTUSII6.0进行仿真.试验结果证明,当弹丸穿过靶平面时,数据采集电路采集的激波信号含有大量噪声,基于FPGA的自适应滤波器能很好地滤除大部分干扰噪声,得到了比较理想的激波数据,提高了报靶系统的报靶精度.

| Abstract: | It is a challenge technology using the shock waves to calculate and indicate the high precision coordinates shotted by a gun in complicate training environment on ouside. In this paper, the shock wave gathered by target-reporting system is processed by using FPGA and adaptive fliting technology. It was programmed by VHDL and simulate by QUARTUS II6.0. It is proved that much more noise can be taken out by the adaptive filter, much better data of shock wave was acquired, the precision of target-repoting syste... |
