Abstract: In this paper, the intention of radar site optimization is proposed. Benefited of the advantage of design and application of site optimization, target can be tracked automatically under complicated clutter environment, The work efficiency of radar system is improved. With the mature of 2D digital phased array antenna, site optimization technique can help the operators carry out multifunctional mission. In the end, the first-class designers must take into account the convenience of manipulator when they plan the site optimization.
