Study on the threshold circuit of a doppler radio fuze receiver fuze receiver

目前空空导弹主动式无线电引信多采用连续多普勒接收方式,而其门限电路的性能对整个接收机的灵敏度等指标都具有至关重要的影响作用。通过分析总结了门限电路的选择依据,给出了一种门限电路原理图。从等效模型的绘制、电路工作流程等方面系统介绍分析了该电路,其经验和分析思路对工程技术人员具有指导意义。

At present, continuous Doppler reception is widely used in air-to-air missile active Radio Fuze,and the performance of its threshold circuit is very important to the sensitivity of the whole receiver. By analyzing and summarizing the selection basis of threshold circuit, a schematic diagram of threshold circuit is given. This paper systematically introduces and analyzes the circuit from the aspects of equivalent model drawing and circuit workflow. Its experience and analysis ideas are of guiding significance to engineers and technicians.
