Abstract
We study the design of radar waveforms and signal processing mimicking the characteristics of biological echolocation. Real biological systems use information in a neighborhood surrounding the response in a process called lateral inhibition, present in neural processing in both the eye and the ear, to sharpen resolution. Any system ignoring the neighborhood response cannot fully exploit the resolution characteristics present in the received signal. Therefore, we investigate neighborhood nonlinear processing using a novel blanker filter. We show that using neighborhood nonlinear processing can separate two targets that are much closer together and the sidelobes are easily reduced. © 2019 IEEE.
