Embodiment Construction

[0046] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0047] Such as figure 1 As shown, the specific steps of the signal coverage analysis method of the present invention are as follows:

[0048] Step 1. Coverage analysis based on ADS-B measured data

[0049] Step A1, classify the ADS-B actual measurement data of flights on different flight levels according to the flight levels classified by civil aviation.

[0050] Step A2. Based on the latitude and longitude coordinates, the Lambert projection method is used to project the ADS-B track points to the Lambert map plane for a given level to form a subset of projected points for the level.

[0051] Apply the Lambert conformal projection method to the flight ADS-B track points...

Abstract

The invention discloses a signal coverage analysis method integrated with ADS-B measured signals and line-of-sight transmission analysis. The method comprises the following content: 1. ADS-B measured signal coverage analysis based on a concave packet model; 2. segment coverage analysis based on a ADS-B signal reliability grade; and 3, ADS-B signal multiple fusion information coverage analysis integrated into a geographic information system. The method provided by the invention is applied to civil aircraft ADS-B surveillance and operation analysis and site selection recommendation. The signal coverage analysis method improves the accuracy of an existing ADS-B surveillance scope and solves the problem of future location and siting of an ADS-B base station.

Description

technical field [0001] The invention relates to a signal coverage analysis method which combines ADS-B measured signals and line-of-sight transmission analysis, and belongs to the technical field of civil aviation ADS-B monitoring and operation safety assurance. Background technique [0002] Automatic Dependent Surveillance-Broadcast (ADS-B for short) is called Automatic Dependent Surveillance-Broadcast System. The system automatically broadcasts the positioning information generated by the satellite positioning system by the aircraft, and also provides information such as speed and flight intention. Ground equipment and other aircraft pass The data link receives this message, and conducts air, space, and ground integrated collaborative surveillance through the high-speed data link. It is especially suitable for areas where radars are not suitable for construction. It is an important part and development direction of the future surveillance system. [0003] The ADS-B (1090ES...
