A new FIR filterbank design algorithm using frequency scaling and modulation (Q1922623)

Digital filterbanks, an important signal processing tool, are used in a radar signal processor to measure target range and/or velocity. This paper focuses on using a wavelet-like scaling approach along with modulation to design a digital filterbank. However, we are not concerned with reconstruction but with the subdivision of the frequency region into a prescribed number of equal segments. It will be shown that this new design algorithm has a frequency response performance comparable to existing techniques but with less computational effort.
