This paper explores the field of multiband radar as a further step in the research into advanced remote-sensing systems with enhanced capabilities. Specifically, a deramping-based multifrequency radar concept is addressed. Several multiband radar architectures are discussed and compared in terms of performances and hardware complexity. For the minimum-hardware multifrequency radar configuration, a proper design for its multiband waveform is suggested which enables the exploitation of all the operation features expected for such a system. Simulated inverse-synthetic-aperture data for a linear-frequency-modulated continuous-wave (LFMCW) dual-frequency radar emphasizes the usefulness and limitations of this multiband radar approach.
