ULTRAWIDEBAND MICROWAVE-RADAR CONCEPTUAL DESIGN

This paper outlines the special considerations that characterize the d esign of an UWB radar for the detection of low-altitude missiles over the sea. It discusses the factors which enter into the choice of frequ ency, and the selection of the transmitter, antenna, and receiver. Rev iewed are signal processing issues concerning detection of UWB signals in noise and clutter, nondoppler MTI based on the pulse-to-pulse chan ge in range due to target motion, measurement of target height based o n multipath time delay, and target recognition. As the investigation p rogressed, the authors became disappointed with the available UWB tech nology, but encouraged about the potential advantages of UWB for this application. The chief limitation of UWB radar that must be overcome b efore applications are viable is its poor electromagnetic compatibilit y (EMC).
