[0034] In order to better understand the present application scheme, the technical solutions in the present application embodiment will be described in connection with the drawings in the present application embodiments.
[0035] In the present invention, the distributed array radar uses a sparse distributed antenna array, combined with the MIMO technology to achieve a wide range of accurate calibration baseline planes, through multiple antenna phase-in-sectic processing instead of the introduction of the accumulated in the ISAR imaging, thereby obtaining real-time imaging capabilities No need to move compensation for the target. Therefore, sparse array instantaneous imaging radar systems can overcome a series of issues such as real-time, limited orientation resolution, and complex motion compensation, and complicated motion compensation. Specifically, such as figure 1 As shown, a spatial high-speed mobile target three-dimensional instantaneous imaging method provided by the prese...
