Accurate distance measurement with a wideband high resolution pseudo noise coded radar

A wideband radar concept with a bandwidth of 3,2 GHz is investigated for automotive application. The wideband direct sequence spread spectrum concept at 24 GHz enables a high resolution with distance cells of less than 0.1 m and an accuracy in the mm-range, a high immunity against interferers and a strong channel separation. A laboratory demonstrator is realised and the feasibility of the concept is shown by way of measured results.
