3D Images of Elevated Automotive Radar Targets at 300GHz

This paper demonstrates the ability of an active 300GHz radar system to perform 3D imaging non-coherently with as few as three receivers. This system was applied to a number of common elevated objects which a road-going vehicle will have to navigate. The large bandwidth of the radar system facilitated full 3D reconstruction using time of flight information alone, applying single-look direct backprojection at a series of azimuth positions.
