Radar working-sequence design for resisting homotypic interference based on clonal selection

For ensuring multiple homotypic radars to work normally together at close quarters, the problem of homotypic interference has to be solved. In this paper, a method is proposed to design radar working-sequence for resisting homotypic interference based on clonal selection. First, limitations of the existed methods are briefly summarized. The relationship between the average homotypic interference and the radar working-sequence is discussed. Then the mathematical model of the optimized radar working-sequence is established to minimize the average homotypic interference. A heuristic search is constructed based on clonal selection to solve an integer non-linear programming problem. According to the experiment results, the clonal selection algorithm converges rapidly at the global optimal solution in high probability, and the best trade-off between the radars efficiency and the anti-homotypic interference performance is achieved.
