Embodiment Construction

[0072] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0073] A kind of formation aircraft conflict detection method of the present invention is according to equation:

[0074] ds dt ( t ) = f ( t ) + w ( t ) - - - ( 1 )

[0075] Where f(t) is a piecewise Lipschitz continuous function defined in [0,∞), w(t) is Gaussian white noise, satisfying E[w(t)w(t+z)]=γ 2 δ(z). (1) is used to model the aircraft motion, where Indicates the movement of the aircraft relative to the ground, f indicates the airspeed of the aircraft, and w models the trajectory estimation error caused by random factors such as instrument accuracy error...

Abstract

The invention discloses a TCAS (traffic collision avoidance system)-based collision detection method for an airplane formation and application of the method. Based on the original airborne anti-collision, the flight path estimation error during a flight is considered, the collision detection method for the airplane formation is introduced aiming at the formation forming process, various random interference factors on performance are considered, an alarm threshold value and a filtering duration probe time are adjustable, better safety is realized compared with the traditional geological probe, and the virtual alarm probability in the formation forming process is effectively reduced, in addition, once an airplane in the formation is deviated from the designated track range, a system provides alarm information and the management and maintenance for the formation are convenient.

Description

technical field [0001] The invention relates to an airborne anti-collision algorithm, in particular to an anti-collision algorithm with a formation algorithm. Background technique [0002] Formation flight refers to the flight of two or more aircrafts maintaining the formation according to the specified interval, distance and altitude difference. It may remain the same for a long time, and if it is not handled properly, it will easily lead to collisions. Therefore, the problem of collision avoidance in formation flight is a direction worthy of research and attention. Keeping formation intervals, distances, and height differences relatively stable is the key to preventing formation aircraft from colliding. One of the important prerequisites. [0003] When the airborne collision avoidance system is working, it automatically sends an interrogation signal compatible with the ground secondary radar to obtain and detect the distance, azimuth, altitude and identification code of t...
