Abstract

The invention discloses a millimeter wave beam forming and detection method. In order to ensure real-time monitoring, the entire monitoring area with a large area is divided into multiple detection sub-areas belonging to different risk sensitivity levels, and the detection radar antenna array simultaneously generates multiple beams to scan and monitor each sub-area. In addition, sub-areas with different hazard sensitivity levels adopt corresponding beam scanning methods through adaptive beam detection algorithms to meet the different requirements of each sub-area for detection accuracy and real-time performance. Due to the different levels of risk sensitivity in each area, the most appropriate early warning strategy can be adopted for each area. With the help of the technical solutions of the embodiments of the present invention, the detection accuracy can be improved, the detection false alarm rate and missed detection rate can be reduced, and the detection efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of disaster and foreign object intrusion detection, in particular to a millimeter wave beam forming and detection method Background technique [0002] my country has a vast territory, complex natural and geographical conditions, and strong geological tectonic movements, which easily induce various geological disasters. Landslides and landslides have occurred in more than 2 / 3 of the mountainous areas in my country. In addition, my country's infrastructure construction is developing rapidly, but some transportation lines such as highways, railways, and tunnels are distributed in concentrated mountainous areas, and geological disasters occur frequently. Once landslides, landslides, mudslides, avalanches, floods, foreign matter intrusion, etc. occur in the mountains next to the road, it will affect the operation safety of the traffic line and pose a direct hazard to the safety of human life and property. Therefo...
