摘 要: | 灵敏度是衡量雷达接收机性能的重要指标,传统非相参体制的雷达通常测试接收机连续波灵敏度。随着全相参脉冲体制雷达的发展,脉冲灵敏度逐渐成为衡量接收机灵敏度性能的主要指标,本文在分析连续波灵敏度测试方法基础上,详细探讨了全相参接收机脉冲灵敏度测试原理,分析了影响脉冲灵敏度测试结果的相参、触发和射频脉冲信号参数设置等因素,结合某型雷达接收机分析了测试实例,论述了测试系统组成、测试过程、注意事项和数据处理等内容,对雷达接收机性能测试与装备保障具有较好的参考意义。

Sensitivity Test Method of Radar Receiver |
| |
Abstract: | The Sensitivity is a very important performance to level a radar receiver. People always test continuous wave Sensitivity when the radar adopted non-coherence mode. With the development of coherence pulse radar, Pulse Sensitivity becomes a more and more important specification to level the kind of radars. Many kinds of factors such as coherence, trigger and parameter settings of radio-frequency pulse which is import for Pulse Sensitivity test are described in this paper. A test case, which includes test procedure, matters needing attention, data procession and etc. for a certain type of radar receiver is prompted. The test method and test instance had referential meaning for radar receiver performance test. |
