Abstract

The invention provides a Doppler very high frequency omnidirectional beacon on-site monitoring system, and the system comprises a radio frequency amplifier unit and a digital signal processing unit; the radio frequency amplifier unit is used for filtering, amplifying and shaping a signal received by a monitoring antenna and sending the signal to the digital signal processing unit for resolving; the digital signal processing unit comprises an FPGA chip, a DSP chip, an RTC chip, an RS232 serial port chip, an FRAM flash memory chip, a FLASH chip, a DA chip and an AD chip; signals received by the monitoring antenna are preprocessed and resolved, and the signals are sent to the main control unit, the remote control unit and the display control unit through the RS232 serial port to monitor the signals of the equipment.

Description

technical field [0001] The invention relates to the technical field of Doppler high frequency, in particular to a Doppler VHF omnidirectional beacon spot monitoring system. Background technique [0002] In recent years, with the increasing number of navigation equipment in airports at home and abroad, the requirements for equipment are also getting higher and higher. The previous generation of Doppler VHF Omnidirectional Beacon is monitored in the far-field mode, and the distance between the monitoring antenna and the station is about 80-200 meters. It occupies a large area, and the maintenance cost of the airport is high. Many difficulties. In response to this situation of the current equipment, relevant R&D personnel have been studying how to solve and optimize it. Contents of the invention [0003] The aim of the present invention is to solve at least one of said technical drawbacks. [0004] For this reason, the object of the present invention is to propose a kind o...
