The paper expresses the Scaled Inverse Fourier Transformation in two or more dimensions. The transformation directly transforms a frequency scaled spectrum back into the non-scaled corresponding counterpart in the space time domain. Hence it is applicable to those imaging processes where the spectrum of the acquired data is a frequency scaled replica radar brightness spectrum, such as mono- and bistatic focusing applications. The transformation makes use of a quadratic form extension of the Bluenstein formula, also known as the Chirped Z-Transform.
