Biologically-inspired wideband target localisation

In this paper we present two biologically-inspired angular localisation techniques for radar which separately use the magnitudes and phases of the wideband received signals as the cues for angular target localisation. By comparison with predetermined map functions, the angle to a target may be estimated with good accuracy and over a wide angular range of operation. These techniques are implemented in a radar system with a single transmitter and two offset receiving antennas, allowing us to draw upon cues derived from biological systems that are often only explored in psychology, biology, and psychoacoustics.
