本报告详细地介绍了模拟测距周制解调器的研制情况,该设备尽可能使用了最近研制的线性集成电路。样机的硬设备可在高噪声环境下(即C/N_0为37分贝-赫)捕获微弱信号的频率和相位,这已在实验室的噪声试验中得到证实。本报告讨论了系统和硬没备的实现情况。这里采用和试验过的测距技术,已直接用于“宇航卫星”系统。这是一种侧音测距的可能途径。试验步骤和试验结果均列在总结、建议和结论等项内容中。报告还给出电路的设计方法、试验数据和分析方法等。 This report describes in detail the development of analog distance measuring week demodulator, the device as much as possible the use of recently developed linear integrated circuits. The hardware of the prototype captures the frequency and phase of weak signals in high-noise environments (ie 37 dB-Hz at C / N_0), as demonstrated by laboratory noise tests. This report discusses the implementation of systems and hardware. The ranging technology used and tested here has been used directly in the “space satellite” system. This is a possible way for sidetone distance measurement. Test procedures and test results are listed in the summary, recommendations and conclusions and other items. The report also gives the circuit design methods, test data and analysis methods.
