摘 要:文章讨论一种遥测信号转发器的设计与实现方法,这种转发器采用再生变频转发方式,接收信号解调后再变频调制发射供遥测地面站接收,可以在不增加转发器发射功率的情况下解决超视距通信问题。该转发器采用软件无线电设计思想,电路采用全国产器件实现,利用国产SOC芯片做为基带处理芯片,国产射频收发芯片实现正交上变频和下变频作为接收与发射通道,通过实验证明了基于全国产芯片的机载遥测转发器能够可靠地工作。This article discusses the design and implementation method of a telemetry signal repeater.This repeater adopts a regenerative frequency conversion forwarding method,which demodulates the received signal and then modulates and transmits it for the telemetry ground station to receive.It can solve the problem of over the line of sight communication without increasing the transmission power of the repeater.This repeater adopts the design concept of software radio,and the circuit is implemented using nationally produced devices.The domestic SOC chip is used as the baseband processing chip,and the domestic RF transceiver chip realizes orthogonal upconversion and downconversion as the receiving and transmitting channels,Through experiments,it has been proven that airborne telemetry transponders based on nationally produced chips can work reliably.
