With this con- figuration, the antenna radiation pattern is maintained for all angles, (which means no beam deformation). Further, the present radar is capable of per- = _ = forming detection at all azimuth and elevation angles with high angle resolu- _ i tion and broadband operation. The radar adaptively adjusts its spatial sensing —= 101 , , e , pattern, sweeping frequency band, pulse repetition frequency and coherent processing interval according to the environment. This is accomplished by initially performing a rough scan, which updates sensing results via a narrow — = = 106 bandwidth waveform and wide beam scanning. When interested objects are = identified, a high- resolution detailed scan is performed in a specific region of interest. In this way, a much more effective detection can be obtained. = _ _ = Moreover, a method of mitigating interference of the 3D printed Luneburg lens based radar and a method of improving the angle resolution using a lens based MIMO approach is disclosed. 104 1 1 102 103 GC kal• 7r '.
