Abstract

Ultra-wideband radar systems provide great potential for radar target detection, identification and imaging through their inherent high-resolution capabilities. This paper considers two applications of a stepped-frequency ultra- wideband radar--detection of targets close to a disturbed sea surface, and imaging of airborne targets. A new technique for target detection is presented, based on the E- pulse concept and designed to eradicate the sea clutter signal while enhancing the target response. A simulation of a missile travelling above an evolving sea-water model is considered, and results are compared to measurements made in an anechoic chamber. Finally, the effects of signal bandwidth and bistatic angle on image resolution are explored, using a time-domain imaging identity with measured, band-limited signals.
