摘要 雷达发射机频率稳定度严重地限制雷达改善因子和可见度。现在连续波频率稳定度测量技术已达很高水平,但现代雷达多半采用脉冲调制体制,射频脉冲序列稳定度是一个新问题。本文给出测试系统原理图、脉间频率和相位稳定度测量方法以及时域、频域测量结果。 Abstract The frequency stability of radar transmitter is closely related with the radar improvement factors and visibility. The measurement technique of CW frequency stability has come up to a high technical level. But most of the modern radar uses a pulse modulation system, the measurement of RF series stability is a new problem. This paper gives the principle diagrams of the measurement system and some methods of measuring the stability of inter pulse frequency and phase. The measurement results in time and frequency domains are given.
