Near Field Imaging of Synthetic Aperture Radiometer

摘要：

The near field applications of synthetic aperture interferometric radiometer (SAIR) are receiving great interest in the recent years. Because the traditional far field Fourier imaging theory can not stand any longer in near field condition, developing the associate imaging theory will be an important objective of SAIR technique. This work is devoted to explore an effective near field imaging method for SAIR systems with traditional far field plane antenna array. The discrete numerical inversion method with focus plane approximation is developed. The Tikhonov regularization method is introduced to deal with the ill condition and measurement errors.
