Abstract
The drive towards higher levels of autonomy requires accurate perception of vehicle surroundings that can be achieved through distributed sensor network. This paper presents a technique of multi-modal sensing with heterogeneous radar sensors using multiple-input, multiple-output and Doppler beam sharpening (DBS) based beamforming. This provides an enhanced azimuth resolution and wide coverage around the vehicle. DBS has a fundamental limitation of reduced field of view (FoV) that depends on platform velocity. Based on radar data replication, unambiguous FoV has been extended to provide higher level of detail about the vehicle. Presented approach has been validated with experimental data gathered using 77 GHz radar chipsets mounted in forward-looking and corner-looking orientations with respect to the platform trajectory.
