摘　　要：捷变频末制导雷达可有效提高武器系统的抗干扰能力,但是作为其专用测试设备的捷变频信号源的计量检定问题却难以得到有效解决。通过分析现有的测试技术,使用通用仪器设备构建测试平台,可实现专用捷变频信号源的自动计量校准。系统采用两路差频形成中频频差的检测方法进行瞬时频率测量,采用单脉冲引频激励测试技术,利用通用测试仪器实现捷变频参数的校准,将捷变频计量技术推向工程应用阶段,可避免通过研制生产专用的计量设备造成其本身难以计量的问题。Frequency agile terminal guidance radar effectively improve the anti-interference ability of the weapon system. Through the analysis of the current testing techniques and construct test platform by using generic equipment and achieve metrological verification of the frequency agile signal source. The system adopted two difference frequency to form intermediate frequency difference detection method to guarantee the precision of instantaneous frequency measure. But the system put forward the innovative single pulse draught frequency excitation test technology, which use the general test instrument to achieve the frequency agile parameter test and it pushes frequency agility measurement technology round to the engineering application stage for the first time, which can avoid the measurement system itself second times measurement problem.
