Abstract :
The modeling of aperture synthesis as a process of Fourier transformation and inversion provides a unified description of synthetic aperture radar (SAR), inverse SAR (ISAR) and hybrid SAR/ISAR techniques. The degradation of the resulting imagery arising from errors in the estimation of target and platform motions and operation in the near field is analyzed clearly and concisely, the results being expressed in a compact matrix form. The verification of this analysis by computer simulation and possible future applications of the formalism developed are discussed.
