Doppler Beam Sharpening for MIMO and Real Aperture Radars at mm-wave and Sub-THz Maritime Sensing

This paper presents a first example of experimental results of the application of Doppler beam sharpening (DBS) to enhance the resolution and detectability of maritime targets at a) 77 GHz using multiple-input multiple-output (MIMO) radar and b) 150 GHz using a real-aperture radar. The performance o...

Description
Summary:This paper presents a first example of experimental results of the application of Doppler beam sharpening (DBS) to enhance the resolution and detectability of maritime targets at a) 77 GHz using multiple-input multiple-output (MIMO) radar and b) 150 GHz using a real-aperture radar. The performance of DBS and MIMO-DBS beamforming have been evaluated with varied platform dynamics and test conditions to highlight the advantages of higher frequencies for the next generation of radar sensors. The applicability of DBS in maritime conditions has also been assessed.
