Waveform-agile sensing: opportunities and challenges

Continuing advances in device technologies are producing active sources that are increasingly agile in their waveform transmission capabilities. Additionally, modern receivers are generally designed to support adaptive processing. This combination presents rich opportunities for new sensing methodologies that exploit the agility of both transmitter and receiver to yield improved performance in such applications as detection, classification, and tracking. The paper outlines some of these opportunities and sketches some challenges entailed in realizing these opportunities and approaches being brought to bear on these challenges.
