79 GHz automotive radar and its opportunities for frequency and bandwidth agile operation

Abstract

Automotive radar sensors typically apply waveforms with a fixed bandwidth. With the new 79 GHz automotive radar band a huge bandwidth of up to 4 GHz has become available, which is an ideal basis for the application of agile waveforms. This paper discusses an approach towards a frequency and bandwidth agile automotive radar sensor that allows to trade maximum range versus resolution. Measurement results of a 79 GHz sensor prototype are shown.
