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...
An automatic measurement device is developed to measure Spectral Bidirectional Reflectance Distribution Function (BRDF) of various samples in the band from 400 to 2000 nm. Spectral BRDF of two kinds of solar panels (silicon solar panel and gallium arsenide solar panel) used on satellite is measured. Spectral Directional Hemisphere Reflectance (DHR) of the solar panels is measured in the band from...
A new optimization technique based on the differential evolution algorithm is presented for the design of two-dimensional synthetic aperture microwave radiometer circle array. The object function is designed by minimizing redundant array and maximizing the distance between spatial frequency coverage samples and the optimal results of 16~32 elements circle array are obtained. Compare with simulated...
