  • Abstract
    To improve further the accuracy in the approximation of the range history for a synthetic aperture radar (SAR) onboard a medium-earth-orbit (MEO) satellite a fourth power term has been added to the advanced hyperbolic range equation (AHRE), and the new one is called a modified AHRE (MAHRE). Then, a two-dimensional spectrum using the MAHRE was derived, and the accuracy of the spectrum analysed. Promising results were obtained.
