The sharedaperture thinned interleaved arrays design technology is an important infrastructure of integrated sensor system (ISS).It can reduce the quantity of antennassave spaceand reduce the loads and manufacture costs.The shared aperture interleaved arrays based on difference sets usually have high sidelobe levelsbecause of the asymmetric distribution of the thinned subarrays elements.A method of optimized interleaved arrays was proposed based on difference sets and genetic algorithm.Firstthe difference sets were used to determine the position of array elementsand the current magnitude distribution of arrays was taken as the decisionmaking variable.The genetic algorithm was used to lower the maximum sidelobe levelthus to improve the performance of the whole shared aperture interleaved arrays.The simulation results show that the method is effective to restrain the sidelobe levels and useful for interleaved array optimization.
