Optimization of synthetic aperture microwave radiometer antenna array distributed on two-dimensional grid points

摘要：

The principle of antenna array distribution of two-dimensional synthetic aperture microwave radiometer is presented. The optimization technique based on differential evolution algorithm (DE) is presented for the design of antenna array. The object function is designed by minimizing redundant array and maximizing the distance between spatial frequency coverage samples ，the stochastic array distributed on two-dimensional grid points are optimized, and the optimal results are obtained. Comparing with two-dimensional regular antenna array, the results show that the optimal array can obtain more spatial frequency samples and larger spatial frequency coverage.
