Flight target threat degree recognition method and system based on entropy weight method, and storage medium

Abstract

The invention discloses a flight target threat degree recognition method and system based on an entropy weight method, and a storage medium. The method comprises the following steps of obtaining radardata which comprises batch starting data of a plurality of flight targets, updating the record chart of the flight target according to the batch starting data, and normalizing the batch starting data, and calculating a threat degree value corresponding to the flight target by combining the batch starting data after normalization processing and an entropy weight method to obtain a threat degree identification result. The radar data is obtained, the radar data is normalized, the threat degree value corresponding to each flight target is calculated by using the entropy weight method, and the recognition result is output, so that the method can effectively assist managers in managing the low-altitude security area, and can be widely applied to the technical fields of detection radar data processing and low-altitude security.

Description

technical field [0001] The invention relates to the technical fields of detection radar data processing and low-altitude security protection, in particular to a method, system and storage medium for identifying threat degree of flying targets based on entropy weight method. Background technique [0002] "Low, slow and small" flying targets (such as aircraft) refer to aircraft and airborne objects that have all or part of the characteristics of "low altitude, ultra-low altitude flight, slow flight speed, and difficult to be detected by radar". The "low, slow and small" refers to "low-altitude, slow-speed, and small-scale flying targets (such as drones)". The flying altitude is generally below 1,000 meters, the speed is relatively slow, and the radar reflection area is small; the flying speed is generally less than 200 kilometers. The radar reflection area (RCS) is less than 1 square meter per hour; therefore, "low, slow and small" flying targets have brought about difficultie...

AI Technical Summary

Problems solved by technology

However, due to the "low, slow and small" flying target flying at low altitude and the track changes rapidly, it is necessary to make a judgment on the "low, slow and small" flying target in a relatively short period of time. To identify threats to flying targets, it needs to be identified manually, which is not conducive to management
