Perimeter surveillance radar in W-band based on vehicle collision avoidance technology

Nowadays, there is an increasing demand for portable and high-resolution radar systems that carry out surveillance functions in hostile environments. There are several works about radar systems in millimeter-wave frequencies for automotive applications and the objective is to go beyond and to develop a lightweight, small and low-cost surveillance radar based on vehicle collision avoidance technology. In this paper, the design of the radar sensor at 77 GHz and the implemented signal and data processing are presented. The sensor is based on hybrid technology: microstrip, waveguide and MMIC. The signal and data processing carries out a Doppler processing and a target tracking.
