Problems solved by technology

One of the difficulties encountered by the mobile FOD radar in the field inspection process is that the roadside lights, bushes, light boxes and other targets outside the runway will cause many false alarms in the radar detection, resulting in too many targets to realize the real runway area. FOD target detection

Abstract

The invention belongs to the technical field of aviation safety, and particularly relates to a radar false alarm target suppression method outside a rectangular runway. The method comprises the following steps: step 1, determining a rectangular coordinate system, and converting rectangular runway area information into a linear equation of four edges; step 2, obtaining radar longitude and latitude information, a radar center line course angle and a radar instantaneous beam scanning angle through a mobile airport pavement FOD detection radar, converting the radar longitude and latitude information into position information of the radar in the rectangular coordinate system and converting the course angle of the radar center line into a deviation angle of a radar scanning center line and a coordinate axis to obtain a radar sight line linear equation; step 3, calculating a distance threshold on the radar sight line according to the linear equation of the four edges and the radar sight line linear equation; and step 4, detecting the target according to the distance threshold on the radar sight line, and realizing radar false alarm target suppression outside the rectangular runway.

Description

technical field [0001] The application belongs to the technical field of aviation safety, and in particular relates to a radar false alarm target suppression method outside a rectangular runway. Background technique [0002] FOD (Foreign Object Debris) on the airport runway refers to any object that appears in an inappropriate position in the airport. This object can scratch the aircraft tires, hit the aircraft fuel tank or the aircraft body, cause the aircraft to slide off the runway, and cause aircraft accidents. Threatening the life and property of passengers, causing flight delays, interrupting takeoffs, and causing huge economic losses. [0003] At present, the detection of FOD at home and abroad basically relies on manual regular inspections. This method is not only inefficient and unreliable, but also takes up the use of the runway, so that the number of flights is forced to be reduced. Moreover, due to human visual fatigue, the missed detection rate is very high. , ...
