Abstract

The development of a new generation of sensors for autonomous vehicles requires the increase of the number of automotive radars on the roads, leading to an inevitable problem of overcrowding of the electromagnetic spectrum in the allocated 77 GHz band. The solution proposed in this research is the migration of the automotive radar operation frequency towards the low-THz band.
This thesis reports, firstly, an experimental study on the feasibility of deploying automotive radars working at frequencies above 100 GHz. The study analyses the possible additional attenuation of the electromagnetic waves in adverse weather conditions and the differences in targets reflectivities, in comparison to the performances of current automotive radars. A comprehensive library of reflectivity signatures of a number of road actors is established, to provide a basis for the development of low-THz automotive radars.
Secondarily, the thesis discusses and demonstrates the advantages of the employment of low-THz signals to improve the imaging capability of automotive radars, to allow identification and classification of road targets based on high resolution images and micro-Doppler signatures.
