Abstract

This paper presents an experimental radar at 35 GHz in development at Daimler-Benz Aerospace, Ulm, Airborne Systems Division. This radar uses FMCW Frequency modulation waveforms with a frequency scanning antenna covering an azimuth sector of more than 30 degrees. Several signal processing algorithms, e.g. CFAR and contrast enhancement, have been developed for different applications. Due to the electronic scanning of the radar beam, an update rate of up to 15 pictures per second can be achieved as required for synthetic vision systems in aircraft. High resolution in both range and azimuth make this design suitable for a wide range of applications. The radar is suitable for use in helicopters or fixed-wing aircraft. Helicopter applications are obstacle warning (including wire detection), terrain avoidance, ground mapping and weather detection. Fixed wing aircraft applications are runway detection including detection of obstacles at the runway and taxiways. The demonstrator is used to verify the functionality of this radar design. Technical data and measurement results will be presented. Based on these measurements the radar performance will be evaluated.
