Abstract
A method for processing detection and range signals using a digital signal processor generates an interstitial filter that overlaps two adjacent baseline filters of filter bank. The interstitial filter is generated from data outputs of the two adjacent baseline filters using computations that are much simpler than those used to generate baseline filters. The inclusion of interstitial filters in the filter bank improves the resolution and signal to noise ratios of the filter bank.
