Wider bandwidths for improved angle and velocity resolution

Angle and velocity are two primary radar parameters where resolution improvements are mostly needed, for detection of targets in complex environments (e.g. multiple targets, severe and wide-spectrum clutter). In this paper, techniques for improving resolution in velocity and angle through widening of the instantaneous bandwidth are examined, and the possibility of complementing such solutions with high resolution processing is emphasized, with two illustrating examples: wideband MTI (Moving Target Indicator) radar, and multiple transmissions system.
