Abstract：How to achievefull coverage of the monitoring area with fewer nodes is the core issue of T-R" multistatic sonar deployment.Bistatic detection area is approximated as two circles in this work．The monitoring area is discretized tooptional positions of the receiving nodes，and an improved nondominated sorting genetic algorithm-II （NSGA-I）is proposed toobtain thePareto front for first optimization.Then the number of receiving nodes is determined basedon thecost-effectiveness ratio threshold and thedual target optimization problem with the minimum number of receiving nodes and the maximum coverage is simplified to a single target optimization problem with the maximum coverage of a certain number of receiving nodes.The virtual force algorithm（VFA）that considers Delaunay triangulation hole repair is provided to twice optimize the deployment positionof receiving nodes. Simulation results show that the proposed method can determine the number of nodes to cover a certain rectangulararea and basically achieve the goal of full coverage through optimized deployment.
