Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] The present invention is a method for identifying maneuvering targets on an airport scene based on a geomagnetic sensor network. figure 1 It is a schematic diagram of the arrangement of AMR geomagnetic sensors. Three groups of AMR geomagnetic sensors are arranged on the runway center line in sequence. Each group contains 2 AMR geomagnetic sensors, and there are 6 AMR geomagnetic sensors in total. Such as figure 1 As shown, the AMR geomagnetic sensor s 1 , AMR geomagnetic sensor s 2 is the first group, and the AMR geomagnetic sensor s 1 , AMR geomagnetic sensor s 2 The fixed distance between them is 5m, and the aircraft / vehicles in the airport scene are the targets to be identified, such as figure 1 shown on the left.

Abstract

The invention discloses an airport surface maneuvering target identifying method based on a geomagnetic sensor network. The method comprises the steps that a plurality of AMR geomagnetic sensors are arranged on a runway centerline to obtain magnetic signals of an airport surface maneuvering target; a time domain method and a frequency domain method are sequentially utilized for extracting an X-axis target signal feature, a Y-axis target signal feature and a Z-axis target signal feature; the X-axis target signal feature, the Y-axis target signal feature and the Z-axis target signal feature are respectively identified to obtain a single-axis identifying result of a single sensor; first-level multi-sensor single-axis data fusion and second-level multi-sensor single-axis data fusion are successively carried out on the single-axis identifying result of the single sensor; a decision is made according to the second-level fusion result to obtain a final identifying result. The complete maneuvering target identifying method based on the geomagnetic sensor network is put forward for the first time and is applied to airport surface maneuvering target identifying; feature parameters are rich, the processed data volume is small, and reliability is high.

Description

technical field [0001] The invention relates to the technical field of airport control, in particular to a recognition method in the field of airport surface maneuver target recognition. Background technique [0002] Due to the number of aircraft take-offs and landings and human errors, runway incursion has become a major hidden danger affecting the safety of the airport scene, and the prevention of runway incursion has become an important issue. The runway intrusion prevention system is divided into three parts: target detection and identification, target tracking and intrusion control. Target detection and recognition, as part of the monitoring function of the system, provides information support for runway intrusion defense through the non-cooperative airport surface movement target detection and recognition method. [0003] The radar surveillance technology and video recognition technology currently used in airport target recognition require a large amount of engineerin...
