8 channel MIMO long range radar concept for angular estimation in multi target scenarios

Abstract

In this contribution a novel concept for a lens based 8 channel MIMO radar is presented. Hereby the sensor concept deals with a combination of optical beamforming based on a dielectric lens and the classical MIMO radar approach to increase the angular resolution. The sensor architecture is presented, the antenna concept introduced and characterized by measurements. After a brief formulation of the signal model, the evaluation of the angular performance based on the Cramér-Rao lower bound is introduced. The paper concludes with the comparison between MIMO and MISO radar processing in real world multiple target scenarios.
