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.
Abstract
This article discusses the design and implementation method of a telemetry signal re-peater.This repeater adopts a regenerative frequency conversion forwarding method,which de-modulates the received signal and then modulates and transmits it for the telemetry ground sta-tion to receive.It can solve the problem of over the line of sight communication without in-creasing the transmission power of the repeater.This repeater adopts the design concept of soft-ware 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 or-thogonal upconversion and downconversion as the receiving and transmitting channels,Through experiments,it has been proven that airborne telemetry transponders based on nationally pro-duced chips can work reliably.
