Abstract

A short range broad band noise radar system using an electrically tunable true-time-delay line in silicon is presented. The delay line has to cover the interested scanning range (here 2.3 m) and show low dispersion. The delay line consists of discrete switchable lines realized in hybrid form and a on chip continual tunable coplanar delay line. The noise radar operates at the X-band (10.7 GHz-12 GHz). Measurements are presented with a fixed obstacle in the scanned range.
