Welti waveforms for high resolution radar
Abstract
The problem of detecting and tracking a small target in a multipath environment is addressed in terms of high-resolution radar utilizing carrier-free signals to discriminate the target from its image in range. A class of carrier-free waveforms referred to as Welti waveforms is constructed from quaternary codes due to Welti. It is shown that such waveforms offer extremely high resolution in range and Doppler. At the same time, large pulse compression ratios can be obtained.
