Abstract :
Nonsinusoidal waveforms with the time variation of a rectangular pulse, received (or radiated) by a line array of sensors (or emitters), yield various antenna patterns which are very attractive for achieving good angular resolution. These antenna patterns, such as peakamplitude, peak-power, energy, and slope patterns, have been derived for various array lengths under a noiseless assumption. The slope patterns are the most attractive for angular resolution. In this paper, line-array beamforming techniques are developed to provide slope patterns for nonsinusoidal signals. The techniques employ sliding correlators (SC´s) for suppressing the additive Gaussian noise present with the received signal, and pulse-shaping processors for determining the slope pattern. Computer simulation is done for deriving peak-amplitude and slope patterns for various array lengths. Also, a method for obtaining monopulse peakamplitude and slope patterns is presented.
