AN/APG-66是一种数字式多功能火控雷达,该雷达是F-16战斗机上的主要传感器。本文介绍了这种雷达工作在中脉冲重复频率(MPRF)脉冲多卜勒下视方式时的检测性能和虚警性能。还介绍了MPRF时的杂波、AN/APG-66雷达的信号处理以及获取性能所进行的各类飞行试验、雷达的计算机模拟和这种模拟的校准。所介绍的检测性能是以飞行试验和经飞行试验校准模拟的输出为根据的。虚警性能则是以飞行试验为根据的,文中还讨论了产生虚警的各种原因。 The AN / APG-66 is a digital multi-function fire control radar that is the primary sensor on the F-16. This article describes the detection performance and the false alarm performance of this radar when operating in the mode of medium pulse repetition frequency (MPRF) Doppler. The clutter at the time of MPRF, signal processing of AN / APG-66 radars and various types of flight tests for acquiring performance, computer simulations of radar and calibration of such simulations are also presented. The test performance introduced is based on the flight test and the flight test calibration simulation output. False alarm performance is based on flight tests, the article also discussed the various causes of false alarms.
