A mathematical model of radar net deployment is established by analyzing the detection performance indicators of radar network.At the same time,an optimal deployment scheme of radar networking based on adaptive opposition-based particle swarm optimization (AOPSO) algorithm is proposed.On this basis,the influence of each performance index on the detection ability in different cases is analyzed by adjusting the weighted value,and the optimal deployment in each case is obtained.The simulation results show that the results obtained by the improved algorithm are better than those obtained by standard particle swarm optimization algorithm,which verifies the feasibility of the mathematical model and the effectiveness of the improved algorithm.
