Embodiment Construction

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indic...

Abstract

The invention discloses an aircraft wake detection system and method based on wavefront information, relates to the field of aircraft wake detection, and solves the problem that the existing aircraft wake detection is difficult to track and analyze the spatio-temporal characteristics of the aircraft wake in a large range. The system includes: an aircraft wake detection system based on wavefront information, including: a base platform and a central control information processing system; Airspace scanning of the area to obtain the distorted wavefront light disturbed by the aircraft; the central control information processing system is used to obtain the wavefront phase of the aircraft wake area based on the distorted wave front light, and reconstruct the turbulent spatial and temporal characteristics of the aircraft wake area , to determine the position of the aircraft that caused the wake. The system and method provided by the invention realize the tracking and analysis of the wake flow of a large-scale aircraft, and provide technical means for aircraft detection and route prediction and planning.

Description

technical field [0001] The invention relates to the field of aircraft wake detection, in particular to an aircraft wake detection system and method based on wavefront information. Background technique [0002] When the aircraft is flying in the atmosphere, the disturbance of the aircraft's wings to the atmosphere produces a wave. Since the wave has an unstable speed, the wave is rotated to form a pair of counter-rotating wings between the aircraft's wings. Vortex, this is the wake of the aircraft. The wake is a strong turbulent flow with obvious characteristics related to the type and volume of the aircraft, in which the air density distribution and diffusion distribution are extremely uneven, with rich spatial and temporal information, and can stay in the air for a long time. Accurately locating the aircraft wake and predicting and analyzing the spatio-temporal characteristics of the wake can significantly improve the flight safety of aircraft and rationally utilize airpor...
