为满足激光驾束制导信息场(简称信息场)的外场检测要求,设计了信息场指令值检测系统并应用于实际检测;采用AVR单片机为数据处理核心,主要对处理好的方波信号进行频率判断和周期计算,计算结果由信号收发单元送至计算机指令值检测界面显示。试验结果表明,信息场指令值检测系统检测精度高、处理时间快,完全可应用于外场检测。

In order to meet the requirements of testing the laser beam riding guidance information field (short for information field) in outfield, a testing system of information field was designed and applied to outfield test. AVR was used as the core processor for data processing which can judge the frequency and calculate the period of the processed square wave, then the processing result was sent to the testing interface on computer by information receiving & sending cell through serial port. It is proved that the testing system of frequency values of information field can be on-site used for its high precision and fast processing.
