Abstract
The use of very short wavelength radar sensors for closed loop
adaptive cruise control (ACC) and obstacle detection has been
demonstrated as part of various international research and
technology demonstration programs (e.g. PROMETHEUS in Europe). The
first radar systems for distance measurement and target tracking
are now under development, with vehicle trials already under way in
several countries.
This paper describes a 77 GHz radar sensor which will begin
production next year (1999) as a headway sensor, initially for use
in cruise control systems. The challenges facing the sensor
manufacturer include the development of robust product designs and
process technologies suited to the high volume and reliability
demands of the automotive market, whilst achieving this at a
sustainable production cost. The key design features of such a
product are described, together with the major factors influencing
cost and performance.
