EMC mobile facility for system level testing of an aircraft

An Integrated EMC Mobile Test Facility (IEMTF) has been designed and developed for system level testing of an aircraft in lieu of dedicated Anechoic Test Facility (ATF). This facility essentially consists of Radiated Emission (RE), Radiated Susceptibility (RS), Bulk Current Injection (BCI), and Ground Plane Interference (GPI) test systems, housed in a mobile shielded shelter. In this paper the system level EMC requirements for aircraft testing have been derived from MIL-STD 464 and related documents. Accordingly the IEMTF has been designed to meet these requirements in the absence of a sophisticated ATF. The details of various test systems with their performance and calibration procedures required in the Open Air Test Site (OATS) for aircraft level EMC testing has been critically discussed in this paper.
