Abstract

The invention discloses a satellite-bone ADS-B (Automatic Dependent Surveillance-Broadcast) interception signal simulator which is used for generating interception analog signals of a satellite-bone ADS-B interception system. The satellite-bone ADS-B interception signal simulator comprises a frequency synthesizer which is used for outputting a frequency source, a modulator and a power amplifier; the modulator which is connected with the frequency synthesizer is used for modulating the frequency source based on ADS-B base band data signals to obtain modulating signals; the power amplifier which is connected with a modulator is used for amplifying the modulating signals and outputting the amplified modulating signals as interception analog signals. The satellite-bone ADS-B interception signal simulator solves the problem that the prior art cannot simulate the working environment of the satellite-bone ADS-B interception system and achieves the effect of the working environment of the satellite-bone ADS-B interception system.

Description

technical field [0001] The invention relates to the field of signal simulation, in particular to an on-board ADS-B detection signal simulator. Background technique [0002] Automatic Dependent Surveillance-Broadcast (ADS-B) uses omnidirectional broadcasting to broadcast air-to-air and air-to-ground reports, and the aircraft automatically transmits its own position to surrounding aircraft, vehicles and ground receiving devices, etc. In addition to realizing air-to-air mutual surveillance and air-to-ground surveillance, other functions can also be realized: air planes can automatically identify mutual positions, maintain distance, and avoid collisions; the ground navigation command system can use ADS-B to communicate with each other. The terminal and the air vehicle implement navigation, surveillance and command; thus, the aircraft, the aircraft on the airport ground, and the airport ground vehicles maintain a certain safe distance, which plays the role of surveillance and col...
