基于多线程数据采集双运动目标测速系统设计及测量精度分析

Measurement Accuracy Analysis of Double Moving Objects Based on Multichannels Data Collection

针对双运动目标的速度测量，用基于网靶和多线程数据采集方法的速度测量，分别从硬件和软件两个部分设计双运动目标速度测量系统，进行了系统的发射试验验证，给出了双运动目标速度试验处理结果。试验结果表明，设计的系统完全满足双运动目标速度测量的要求，且具有反应速度快、自动化程度高、实用等优点。

According to measurement of double moving objects, based on ＇net targets and multichannels data col- lection average velocity method, a measurement system of double moving objects is designed including hardware and software. Through launching test of the system, and the measurement error analysis of double moving ob- jects, experimenterly the results are obtained, showing that the system meets requirements of double moving ob- jects speed measurement accuracy.
