Environmental constraints-based location optimization method for radar station

Abstract

The complex geographical environment and electromagnetic interference environment within the radar deployment position area will seriously degrade the radar detection performance. Focusing on the urgent requirement of optimizing radar deployment in complex geographic and electromagnetic environments, the environment-constrained radar position positioning optimization method is investigated. Firstly, based on the terrain and electromagnetic interference environment of radar positions, a radar position selection method under both geographic and electromagnetic environment constraints is established. Then the propagation loss under complex geographical terrain is calculated by combining the radar equations, and the detection power of target height layer and the coverage power of the focused area are used as the evaluation indicators for the superiority of radar sites. Finally, the detection range of the radar under multiple environmental constraints is visualized. The problem of complex radar operational scenarios in real systems and the single constraint considered in traditional radar equipment deployment methods is addressed. By calculating the propagation loss, terrain loss, electromagnetic loss under multiple environmental and electromagnetic constraints, and adding actual elevation and terrain data as reference, a more realistic and objective analysis of the impact of the environment around the position on the performance of radar equipment is provided, and finally the evaluation indexes and selection methods is proposed in this paper. The proposed evaluation indexes and selection methods and visualization can provide accurate, reliable and intuitive strategies for optimizing the deployment of radar equipment under multiple constraints.
