文摘

MIMO radar has received significant attention to radar communities recently. This paper presents a novel scheme for wide-swath and high-resolution synthetic aperture radar based on a MIMO UWB-OFDM system. The swath is increased based on a new approach for orthogonal pulse-shaping and MIMO wide-swath SAR topology. The resolution is improved using UWB-OFDM waveforms. Performance is further enhanced using image fusion techniques to benefit from the potentials of multi-sensor imagery such as noise level reduction.
