为了满足无线电引信对多普勒信号测试的需求,提出了一种基于DSP和LabVIEW的无线电引信测试系统。该系统利用多普勒信号发生器模拟弹目交汇时产生的信号,并将该信号输入引信,最后通过LabVIEW软件平台,观测引信的状态并判断引信是否能正常作用。系统结构简单,使用LabVIEW软件取代了昂贵的测试设备,节省了人力、物力。实验结果表明,系统运行稳定,测试效率高,测试结果准确可靠。

In order to meet the requirement of radio fuze testing for Doppler signal, a testing system based on DSP and LabVIEW of radio fuze was proposed. The system uses signal generator to simulate the signal by projectile-target encounter, inputs the signal into the fuze, and observes the fuze's status and judges whether the fuze works normally or not on the LABVIEW software platform. This system has a simple structure with virtual instrument software instead of expensive test equipment to economize labour and materials. The results show that this system runs steadily and has a high testing efficiency and accurate result.
