| Abstract: |
| The optimal search problem of phased array radar based on early warning aircraft guidance is researched in this paper. The targets are classified from the perspective of fighter radar search based on the early warning aircraft guidance. In order to improve the existing radar optimal search model，new search constraints based on the actual combat requirements are proposed. And a two-step optimization strategy is presented to resolve the optimization problems in different search stages. The method of convex optimization is used to solve the optimal search model. Lagrange method combined with barrier method is proposed to solve the multi-constraint and multi-objective problem in real-time，which has greater engineering application value. Finally，simulation is used to verify the validity of the method. |
