通信搜索接收机性能分析与仿真

Analysis and Emulation on Communication Scanning Receiver

截获概率、搜索速度、测频灵敏度以及对捷变信号的截获能力是通信测频搜索设备的重要技术指标。首先对通信搜索接收机的几个重要技术指标进行分析,然后在仿真研究的基础上按实际系统构造通信搜索接收机模型,并对模型进行仿真实验。结果表明,本仿真系统可以对搜索接收机设计方案进行定量分析、比较,高效简便地进行接收验证和性能评估。

Probability of interception of a radio transmission, scanning speed, sensitivity of measuring frequency and interceptive ability for radio signal that varies swiftly are techno--qualities of reconnaissance equipment. Based on emulate studying,the paper builds a emulate model of communicate scanning receiver and makes emulate experiment. The results indicate that the emulate system can analyse and compare the design project quantificationally, can conveniently validate receiving signal and evaluate capability of scanning receiver.
