Remote sensing and monitoring global target space coverage optimization method

Abstract

According to the remote sensing and monitoring global target space coverage optimization method disclosed by the invention, aerial targets in a certain height range can be effectively sensed. The method can be realized through the following scheme: firstly, screening out sensors capable of sensing a to-be-sensed target space, forming a three-dimensional space directed sensor network of sensing coverage, and establishing a set coverage model; counting the coverage range of discrete points of the three-dimensional to-be-sensed space, calculating the sensing coverage rate, and iteratively optimizing the fitness function. The directional sensors are adjusted to solve the sensing coverage rate of the whole directional sensor network to the space to be sensed, the pitch angle and the azimuth angle of each sensor are iteratively optimized by using a random search algorithm, and the specified three-dimensional aerial target on the earth surface is sensed and covered until the coverage rate requirement or the iteration frequency requirement is met. Optimizing parameters are output through the intelligent optimization algorithm to adjust the azimuth angle and the pitch angle of the sensor, and global optimal space coverage is obtained by optimizing the main sensing direction.
