Down-Range Imaging of Radar Targets

Abstract

A derivation is given of the one-dimensional, down-range image of a radar target in terms of the discrete Fourier transform (DFT) of the target returns at each of a number of equally spaced radar frequencies. The formula for the image is applied to return signals computed for point targets. In general, as long as the points are separated by at least 1.5 resolution cell widths, and their reflectivities differ by no more than a factor of 2, the images yield fairly accurate information on both the relative location and reflectivity of the points of the target.
