Abstract:

Electronic Support Measurement Systems and Systems for Electronic Counter Measures of military aircraft require antennas for signal transmission and reception. The coverage of these antennas is an important parameter in the effectiveness of the systems. As the radiation patterns of aircraft antennas are interfered to a high degree by the structure and configuration of the aircraft, flight tests are conducted in order to prove the coverage of the above-mentioned systems. In addition, the accuracy of ESM systems, is mostly influenced by the characteristics of the receiving antennas and hence has to be determined in flight too. The Institute of Flight Guidance of DFVLR has developed a system which covers the afore-said requirements. It consists oof 3 subsystems 1 a ground emitter system illuminating the target up to frequencies of 18 GHz 2 an on-board receiving system, which detects the signals received by the antennas of the system under test and 3 a data acquisition and transmission system, which transfers on-board and ground data to a digital computer for quick-look and data processing.
