FOD detection radar system

Abstract

The invention relates to an FOD detection radar system. The FOD detection radar system comprises an antenna feeder subsystem, an intermediate frequency subsystem, a digital subsystem, a power subsystem and an auxiliary debugging system, wherein the antenna feeder subsystem comprises an antenna and a receiving-transmitting front-end; the antenna comprises an antenna support, a transmitting antennaand a receiving antenna; the intermediate frequency subsystem mainly comprises a transmitting frequency synthesizer, a local oscillation frequency synthesizer and a receiver / LFM source; the receiver / LFM source provides a homogenous LFM signal for the transmitting frequency synthesizer and the local oscillation frequency synthesizer, meanwhile receives an output signal of a receiving link of the receiving-transmitting front-end and outputs the output signal to a signal processor after frequency conversion; the digital subsystem comprises the signal processor and a communication interface module; the signal processor is a core component of the system, is connected with an upper computer system of an airport and receives control information of the upper computer system; and the communicationinterface module is used for converting the signal of the signal processor and performing communication between an FOD detection radar and the upper computer system. The FOD detection radar system hasthe advantages of being small in size, stable in performance, high in practicability and high in anti-interference capability.

Description

technical field [0001] The invention belongs to integrated circuit embedded application products of electronic information technology, and specifically relates to a FOD detection radar system. Background technique [0002] FOD is the abbreviation of Foreign Object Debris, which generally refers to certain foreign substances that may damage aircraft or systems, often called runway foreign objects. There are quite a few types of FOD, such as aircraft and engine connections (nuts, screws, washers, fuses, etc.), machine tools, flying objects (nails, personal documents, pens, pencils, etc.), wild animals, leaves, stones and sand, Pavement materials, wood blocks, plastic or polyethylene materials, paper products, ice debris from operating areas, etc. [0003] The harm of FOD is very serious. Experiments and cases have shown that foreign objects on the airport pavement can be easily sucked into the engine, resulting in engine failure. Debris can also build up in mechanisms, affec...

AI Technical Summary

Problems solved by technology

In our country, there is no report about the successful development or trial use of radar or video systems for FOD monitoring. The monitoring of FOD at airports is based on manual regular inspections and close-range search by human eyes. This backward method has low efficiency and poor reliability. Moreover, it takes up precious runway use time greatly, so that the number of flights is forced to be reduced
