Research work in the area of phased-array radar has been performed at the research institute FGAN-FFM (now Fraunhofer-FHR) since 1970. The phasedarray system ELRA (electronic steerable radar) served as an experimental basis. The first successful radar operation with the tracking of flying targets dates back to the year 1975. Since then many modifications and further developments corresponding to the advances in theoretical knowledge and in technology havebeen made in the areas of hardware and software. Most of the new concepts described in this book have already been implemented and tested in the ELRA system. The main effort has been concentrated in the areas of signal and data processing and system control.
