Embodiment Construction

[0041] figure 1 Among them, 1: the first direction-finding base station; 2: the second direction-finding base station; 3: the third direction-finding base station (generally three direction-finding base stations can be used); 4: data processing center; 5: target.

[0042] figure 1 Among them, the line between the direction-finding base station and the target represents directional detection, and the line between the direction-finding base station and the data processing center represents data connection. The present invention consists of a data processing center and multiple direction-finding base stations. Each direction-finding base station passes through The data line is connected with the data processing center; the direction finding station is composed of a directional antenna, a servo device, an ADS-B signal receiver and related equipment.

Abstract

The invention relates to a method for detecting an automatic dependent surveillance-broadcast (ADS-B) false target, which belongs to a method for measuring a target location by an air traffic management system so as to judge whether a target is the false target or not and comprises the following steps: reading target representation and four-dimensional location (time, longitude and latitude, height) information output by an ADS-B system by a data processing center firstly, and respectively sending to a plurality of direction-finding base stations; firstly enabling a directional antenna to point to an orientation in which the target is located by the servo devices of all the direction-finding base stations, then, receiving target information from the direction by using an ADS-B receiving machine according to the synchronizing signal of the data processing center, and sending the target information back to the data processing center; and analyzing the results of all the direction-finding base stations by the data processing center, if more than two direction-finding base stations are capable of respectively receiving the target information, showing that the target is real; and if the target information is received by only one station or no station, showing that the target is false. In the method for detecting the ADS-B false target, a multi-station direction-finding system is formed, thereby, the false target can be accurately and effectively judged, the hidden danger is eliminated, and the air traffic safety is guaranteed.

Description

technical field [0001] The invention relates to the field of air traffic management. Specifically, it is a method of using directional antenna receiving technology to measure the position of the target in the Automatic Dependence Surveillance-Broadcast (ADS-B: Automatic Dependence Surveillance-Broadcast) system to determine whether it is a false target. Background technique [0002] In the field of air traffic management, ADS-B is an inexpensive surveillance technology, which enables the monitored (including aircraft or ground vehicles and other targets that need to be monitored, also known as targets) to actively send their own identification through the data link of the broadcast mode and precise four-dimensional position data, so as to achieve passive surveillance. Compared with traditional radar surveillance technology, ADS-B not only has timely data (data interval can reach 1 second, while traditional radar data is 4-12 seconds), but also accurate positioning (ADS-B us...
