A Hardware Design Method for Regenerative Airborne Telemetry Repeater
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.
