Problems solved by technology

However, due to the complex electromagnetic environment characteristics of the city, millimeter-wave radar can detect other interference targets that have nothing to do with high-altitude parabolic objects, which poses a greater challenge to the judgment of high-altitude parabolic behavior

Abstract

The invention discloses a high-altitude parabolic object detection and discrimination method based on millimeter wave radar data fitting. According to the method, a suspicious parabolic area of a high-rise building is monitored in real time through a millimeter-wave radar system, a distance-Doppler detection track of a moving target is obtained, and a distance-Doppler characteristic curve of the moving target in radar detection is used for discriminating a high-altitude parabolic behavior. And performing fitting processing on the distance-Doppler trajectory of the moving target after clutter suppression and a simulation characteristic result of classical mechanical parabolic motion, and judging whether a high-altitude parabolic behavior occurs or not. The invention effectively provides the method for judging the high-altitude parabolic trajectory by the millimeter wave radar, and the feasibility and reliability of evaluating the high-altitude parabolic behavior are greatly improved.

Description

technical field [0001] The invention relates to the fields of millimeter-wave radar detection and urban security, in particular to a method for detecting and judging high-altitude parabolic objects based on millimeter-wave radar data fitting. Background technique [0002] The monitoring of high-altitude parabolic objects is the key to preventing and deterring high-altitude parabolic behaviors. Both academia and industry have conducted related research on this issue. The existing high-altitude parabolic monitoring means are based on visual detection technology. However, the high-altitude parabolic monitoring scheme based on vision is extremely susceptible to environmental factors, and its performance deteriorates seriously in darkened (night) or extreme weather environments (fog, sand, etc.). [0003] The basic principle of radar determines that it has natural advantages in monitoring moving targets. Millimeter-wave radar works in the millimeter-wave (30-300GHz) frequency b...
