Creating and processing universal radar waveforms - US Patent 8593338 Full Text

FIG. 1 compares plots of various universal radar waveform (URW) sampling patterns of length 41, including a full pattern, a first-half pattern, an alternating pattern, a quadratic residue (QR) pattern and a pseudo-random pattern.

Abstract

A new approach to radar imaging is described herein, in which radar pulses are transmitted with an uneven sampling scheme and subsequently processed with novel algorithms to produce images of equivalent resolution and quality as standard images produced using standard synthetic aperture radar (SAR) waveforms and processing techniques. The radar data collected with these waveforms can be used to create many other useful products such as moving target indication (MTI) and high resolution terrain information (HRTI). The waveform and the correction algorithms described herein allow the algorithms of these other radar products to take advantage of the quality Doppler resolution.
