Embodiment Construction

[0021] As shown in Figure 1, the data evaluation overall process of the ADS-B monitoring technology of the present invention comprises 5 modules: ADS-B aircraft ratio statistics module, monitoring accuracy evaluation module, reliability evaluation module, data integrity evaluation module and pseudo Target probability evaluation module, its processing flow is as follows:

[0022] (1) ADS-B aircraft proportion statistics module

[0023] This module counts the proportion of aircraft currently equipped with ADS-B airborne equipment, and judges the number of ADS-B aircraft by receiving the broadcast ADS-B data from the aircraft through the ground station. The specific implementation is shown in Figure 2: First, the ADS-B data collected during the entire evaluation flight phase is extracted from the database server, and then based on receiving the broadcast ADS-B data from the aircraft through the ground station, that is, the ICAO address of the aircraft, calculate and send the ADS-...

Abstract

A data assessment system for ADS-B monitor technology is provided, which comprises an ADS-B airplane scale statistics module that keeps statistics of airplane scale with ADS-B airborne equipments and judges the number of ADS-B airplane, a monitor precision assessment module that assesses the precision of ADS-B position message data, compares the variance between ADS-B, radar position data and standard position in same time section and works out the conclusion of monitor precision, a reliability assessment module that assesses the reliability of ADS-B monitor data, calculates separately the missing dot rate of radar and ADS-B monitor data in same time section, compares them and reaches the conclusion about the reliability of ADS-B monitor data, a data integrity assessment module that assesses the integrity of ADS-B monitor data, a fake object possibility assessment module that assesses the fake object possibility of ADS-B position message data and works out the conclusion about the fake object possibility of ADS-B monitor data. Therefore, the invention, which is easy to be implemented in engineering, effectively realizes the data assessment for ADS-B monitor data.

Description

technical field [0001] The invention relates to a data evaluation system of monitoring technology, in particular to a data evaluation method of ADS-B monitoring technology, which belongs to the field of air traffic control. Background technique [0002] The fundamental purpose of air traffic control is to make the aircraft on the route safe, effective and planned to fly in the airspace, and the controller needs to monitor the flight dynamics of the aircraft in the controlled airspace in real time. [0003] The traditional radar surveillance method adopts the way of inquiry and response to detect the target. In the long run, the radar system itself has many limitations, which limit the improvement of surveillance performance. The straight-line propagation of the radar beam forms a large number of radar blind spots, which cannot cover areas such as oceans and deserts; the radar rotation period limits the improvement of the data update rate, thereby limiting the improvement of...
