本文介绍一个用于靶场的火炮弹丸测速系统,通过自己研制的接口卡、回波锁相跟踪线路板使APPLE-Ⅱ微机与多普勒测速雷达连在一起。利用对话方式由操作员设定测速的各种要求和初始条件,从雷达接收机送来的连续多普勒正弦信号在微机的控制下被录取为速度数据,处理后计算出初速度、平均速度、散差、斜距,按操作员的意图输出V-T数据表、S-T数据表、实测的和标准的速度变化曲线。每次可测15发弹丸,每发50点的数据。系统功能齐全,使用灵活,对研究整个炮弹的性能、弹道特性有着重要意义。
In this paper, an artillery projectile velocimetry system for shooting ranges is introduced. The APPLE-Ⅱ microcomputer and Doppler velocimetry radar are connected together by the developed interface card and echo phase-locked tracking circuit board. Dialogue mode by the operator to set the speed requirements and initial conditions, from the radar receiver to send continuous Doppler sinusoidal signal under the control of the computer was admitted as speed data, calculated after the initial speed, the average speed, Scattered poor, slant range, according to the intentions of the operator output VT data sheet, ST data sheet, measured and standard speed curve. Measurable 15 rounds of projectiles each time, each made 50 points of data. The system is fully functional and flexible to use. It is of great significance to study the performance and trajectory characteristics of the entire shell.
