查询词典 anechoic chamber

These methods are validated using simulation data, data measured in microwave anechoic chamber and practice measured PolSAR complex imaging data. Unlike the traditional method, these methods can estimate coherent scattering matrices of scattering centers accurately by overleaping the step of scattering center association.
