Low-altitude flying target warning system and method based on Beidou satellite navigation system

Abstract

The invention provides a comprehensive flight safety warning system and a comprehensive flight safety warning method, which can be used for performing safety monitoring and command guide on a low-altitude flight target, performing threat comprehensive estimation and real-time warning, based on a Beidou satellite navigation system. By adopting the Beidou satellite navigation system, not only can three-dimensional positioning information of a flight target be provided, but also the flight parameters can be transmitted, so that a good technical supporting platform is provided for realizing comprehensive warning application. On the premise of comprehensively analyzing various security threats, real-time safety warning is realized on the low-altitude flight target; for direct safety threat warning, not only is most-concerned course front height warning in the flight track reflected, but also terrain perception, threat estimation and safety warning are performed at the left and the right sides of the flight object through a barrier warning method, so that the barrier perception and warning system around the flight target is perfected. Through the realization of the barrier warning method, a safe navigation track is planned, and the safety of the whole flight pipeline is further ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a low-altitude flying target warning system and method based on the Beidou satellite navigation system. Background technique [0002] In the field of aviation, the flight process is divided into ultra-low-altitude flight, low-altitude flight, medium-altitude flight, high-altitude flight and ultra-high-altitude flight according to the flight height, as shown in the table below. [0003] [0004] Low-altitude flight usually refers to the flight from 100m to 1000m from the ground or water surface. Whether it is in military applications or civilian applications, low-altitude flight is very common. For example, in the military field, the parachute of armed helicopters, equipment airdrops, armed reconnaissance, fighter jets' assault, penetration assault, etc.; important role. Due to the low flying altitude of the aircraft, low-altitude flight can reduce the detection rate of...

Problems solved by technology

Generally speaking, there are two deficiencies in the monitoring systems currently on the market: one is that monitoring is carried out in two-dimensional maps, which is not sufficient for the monitoring of movements in three-dimensional spaces such as aircraft; the other is that the system functions are relatively single, mainly monitoring Target trajectory display and short-message communication are the main focus, lack of comprehensive judgment and real-time warning of the safety status of the monitoring target, and the safety warning of low-altitude flying targets only focuses on the warning of flight into the ground, while the situation of the air situation and the composition of terrain and landform Insufficient consideration of direct safety threats, as well as indirect safety hazards constituted by mission areas and flight path planning, leads to unsatisfactory auxiliary decision-making information, which easily leads to misjudgment and safety flight accidents
