Topology Optimization with Multiple Discrete Variables in Large Phased Array Radar

Abstract

According to the trend of maximization of phased array radar,a layout optimization with the position of supporting points and stiffeners is set up considering the power compensation to the subarray.The supporting points are selected from a finite number of locations allow installed,simultaneously,the contribution of the topology of the stiffeners is considered.For the aim of the best-fit root mean square,under the restriction of the maximum mass and stress,an optimization model is established.A continuous step function constructed to map the discrete variables to continuous variables can avoid the straightforward use in discrete variables,and the corresponding computing cost is lower.A large phased array radar is selected to verify the proposed method.A satisfied result is obtained and will be applied into the engineering.
