Digital Array Radar (DAR) has the ability of simultaneous multimode imaging and has many potential applications. This paper firstly introduces the basic hardware structure and the operation principle of DAR. Combined with the Digital BeamForming (DBF) technique, six operational modes that can be used in multimode Synthetic Aperture Radar (SAR) imaging are proposed, and the corresponding novel imaging modes are produced. Moreover, the design of the novel imaging modes is introduced in detail. The simulation results confirm the efficiency and precision of the imaging modes.
