  In this paper, considering multiple interference regions simultaneously, an
optimal antenna deployment problem for distributed Multi-Input Multi-Output
(MIMO) radar is investigated. The optimal antenna deployment problem is solved
by proposing an antenna deployment method based on Multi-Objective Particle
Swarm Optimization (MOPSO). Firstly, we construct a multi-objective
optimization problem for MIMO radar antenna deployment by choosing the
interference power densities of different regions as objective functions. Then,
to obtain the optimal deployment result without wasting time and computational
resources, an iteration convergence criterion based on interval distance is
proposed. The iteration convergence criterion can be used to stop the MOPSO
optimization process efficiently when the optimal antenna deployment algorithm
reaches the desired convergence level. Finally, numerical results are provided
to verify the validity of the proposed algorithm.
