Expressway vehicle sensing system and method based on space channel detection

Abstract

The invention discloses an expressway vehicle sensing system and method based on space channel detection. An unmanned aerial vehicle space channel detection method is used, and expressway multilane and multi-vehicle real-time scanning detection is performed through a receiving and transmitting antenna array arranged at the bottom of an unmanned aerial vehicle detector. According to the analysis on the variation characteristics on a space moving channel, multi-dimensional parameters of the moving channel can be obtained in real time, and the position, the speed and the vehicle type of moving vehicles on an expressway are accurately estimated. The expressway vehicle sensing system and method based on space channel detection break through the limitation of vehicle sensing based on traditional sensors such as an infrared sensor and a video sensor, an advanced space moving channel detection and vehicle sensing technology is utilized, the all-weather vehicle sensing capacity in the intelligent transportation system application is improved, and the expressway rod vehicle sensing system and method based on space channel detection can be applied to the fields of intelligent transportation system air control, expressway traffic dispersion, after-calamity traffic guidance control, military exercise air monitoring and the like.

Description

technical field [0001] The invention belongs to the field of vehicle networking communication of an intelligent transportation system, and relates to an expressway vehicle perception technology based on space-ground channel detection. Background technique [0002] The transportation system is a typical complex system.
