“…In recent years, synthetic aperture microwave radiometer has been the research focus in passive microwave remote sensing, and occupies an increasingly important position [ 1], Microwave radiometer widely used in sounding, temperature measurement and other remote sensing applications, it has still more advantages, such as miniaturization, light weight and low power consumption, it can work at all weather condition. Aperture synthesis has been successfully employed in radio astronomy to obtain very high resolution maps of radio sources.…”

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.Index Termstwo-dimensional synthetic aperture microwave radiometer; antenna array optimization; differential evolution algorithm
