Abstract

A first attempt at side lobe suppression by amplitude-thresholding each plotted correlation function was reported. The results showed that, whereas the side lobe tracks could be eliminated by amplitude-thresholding, many of the true correlation peaks were also lost, especially at the lower aspect values (near beam), thus degrading the true track. Subsequently further attempts to achieve side lobe suppression by signal weighting, or by different processing, were performed. The Hamming weighting function, given by omega(t,alpha) = alpha + (1-alpha) cos (2pi/T), was used. The parameter T is the signal length; alpha is a constant which describes the functional pedestal.
