Problems in ISAR Processing with Range Resolution by Stepped Frequency Bursts,

Abstract

If a target image is reconstructed from an ISAR measurement by immediate application of the Discrete Fourier Transform, the image becomes blurred with increasing distance from its center. It is shown that with an ISAR sensor applying stepped frequency bursts, samples of the 2-dimensional Fourier Transform of a 2-dimensional scatterer density are measured and how a target image can be reconstructed.
