Study on sparse microwave imaging

Sparse signal processing is introduced to microwave imaging technology, which forms a new theory, new system and new methodology in microwave imaging. Defined as sparse microwave imaging, it means that by the sparse domain representation of the observed object, the sparse microwave signal is acquired by sparse sampling in space or time domain. After the signal processing and information extraction, the geometrical and physical characteristics of the observed object can be acquired with lower data rate and less hardware complexity of the imaging radar.
