The DLR static multisensor short range radar for surveillance of ground traffic on airports

The modular structured DLR near-range radar network (NRN) has been designed as a noncooperative sensor component for integration into the multisensor fusion of a surface movement guidance and control system (SMGCS) on airports. The functional characteristics and the structure of a single radar station are discussed. Due to sophisticated processing echo signals of expanded pulse targets with a backscattering cross section of 1 m/sup 2/ can be detected at a distance of 1 km using fixed, nonrotating antennas having broad sector characteristics in the azimuth and low power transmitters. From the complex valued echo profiles, measured by the four stations of an NRN module, the so-called rolling status for a plurality of targets including target classification can be derived. The present status of the development are presented and the remaining work are sketched.
