用数字计算机控制雷达系统和实时监控其性能已有二十年了。这类控制功能包括诸如产生波形和接收雷达回波这样的简单处理,到产生雷达命令表和完成校准这样的复杂处理。但是,诊断和性能监控技巧只是在最近才成熟到与控制技巧一样完善的程度。这种滞后现象在很大程度上是由于程控数字硬件目前的技术水平,以及对联机诊断活动与脱机测试形成的一个连续处理谱缺乏理解造成的,而这种联机诊断活动并不是什么特别的处理功能。 It has been twenty years since the digital computer was used to control the radar system and monitor its performance in real time. Such control functions include simple processes such as generating waveforms and receiving radar echoes, and complex processes such as generating radar command lists and completing calibration. However, diagnostic and performance monitoring techniques have only recently matured to the same degree as control techniques. This hysteresis is due in large part to the current state of the art digital hardware and the lack of understanding of a continuous spectrum of on-line diagnostics and off-line testing that is not unique Processing functions.
