Radiometric Correction and Calibration for Low Frequency UWB SAR System
Abstract
The new peculiarities of the low frequency UWB SAR result in difficulty of radiometric correction and calibration for the system. The calibration techniques developed for common high frequency and narrow band SAR system cannot be applied to the low frequency UWB SAR. In this paper, based on the peculiarities of the system, the system processing model and the electromagnetic scattering model of calibrators are given, and the new radiometric correction and calibration method is proposed. The computer simulation is used to validate the method.
