Digest to the Workshop on New Component Technologies for Vehicular Radar Applications at the International Microwave Symposium 2009 (IMS)
Recent achievements in the integration of mm-wave radar-systems have led to many new applications and features. An outstanding development is the integration of multi-channel systems, which allows the utilization of beamforming and/or phased array techniques for mass market applications. Nevertheless, standard sensor concepts offer only limited performance in such systems, due to the restrictions imposed by the need for low-cost solutions. This contribution will give an introduction to standard beamforming concepts applied to FMCW radar sensor concepts. Furthermore the limiting factors of conventional approaches will be shown. Various methods to overcome these limitations will be discussed. By means of a prototype operating at a frequency of 77 GHz, the emerging MIMO-radar technique will be illustrated. The talk will cover multiple aspects of radar sensor design and signal processing algorithms.
