Abstract

The invention discloses a 1090ES-mode ADS-B receiver with a USB interface. The 1090ES-mode ADS-B receiver comprises a radio frequency front end and a video processing unit which are connected; the radio frequency front end is used for receiving antenna signals and comprises a low-noise amplifier and a logarithmic amplifier which are connected in sequence; the video processing unit comprises an RC integral circuit for receiving signals output by the logarithmic amplifier and a single chip microcomputer module connected to the output end of the RC integral circuit; and the single chip microcomputer module is provided with an external port and a comparator, a PWM signal output port of the single chip microcomputer module is connected with the inverted input end of the comparator through an external filter circuit, the positive input end of the comparator is connected with the output end of the logarithmic amplifier, and the output end of the comparator is connected to a digital input port of the single chip microcomputer module. The 1090ES-mode ADS-B receiver can be used for acquiring related flight data carried by 1090Mhz radio signals sent by an airplane and is low in price and small in size.

Description

technical field [0001] The invention relates to the field of aviation settings, in particular to a 1090ES mode ADS-B receiver using a USB interface. Background technique [0002] ADS-B, Automatic Dependent Surveillance-Broadcast, is a new-generation technology that integrates communication, satellite navigation and surveillance technologies promoted by the International Famous Aviation Organization. It is also an application system based on aircraft surveillance technology and an important component of the new-generation air traffic management system. part. ADS-B information is broadcasted through air-air, air-ground and ground-ground data links in the form of ADS-B messages. Most aircraft are currently equipped with 1090MHz Mode S transponders. By receiving the signal, relevant flight data of the aircraft can be obtained. However, the existing professional receiving equipment is bulky and expensive. Contents of the invention [0003] In order to solve the above techni...
