Reduced bandwidth algorithm for near field imaging of tree targets using synthetic aperture radar

摘要

An imaging algorithm which can generate high resolution near-field synthetic aperture radar images is presented. The algorithm requires only a small fractional bandwidth and is not computationally intensive. Images are produced in a format familiar to the human visual system and provide amore complete characterisation of the polarimetric scattering distribution of a target. A new derivation of the algorithm is presented and its characteristics and limitations are described And formulated.
