摘　　要：为了实现远距离、非接触方式对爆炸容器的高速变形过程进行测量,项目研究了激光多普勒动态位移测量系统;但是随着试验任务要求的不断提高,现有激光多普勒动态位移测量系统一些技术指标(量程、分辨率)不能满足测试要求的现状,通过信号分析方法的研究,在不改变硬件的条件下,改进信号处理方法,重新研制数据处理系统,挖掘原系统的潜力,扩展原有测量系统的量程,并提高测量对象的分辨率;实验结果表明,该数据处理系统运行稳定可靠,检测精度高,其信号处理方法是可行的。In order to realize long--range and non--contacted measurement of the high--speed deformation process of the explosive container, the measurement system of Laser Doppler dynamic displacement was developed. Due to some of technique parameters can＇t satisfy tes- ting request in the Laser Doppler displacement system, such as range and resolution, so in order to increase test system range and resolution, with improving signal processing technique, new data processing system is developed, on the condition of unchanged system hardware. The experimentation shows that this data processing system runs stably and accurately, the signal processing technique adopted in the system is feasible.
