Abstract:

The intent of this effort was to measure the interference susceptibility of present-day ADF equipment and to determine if RTCA and ICAO documents dealing with this subject are still representative. The results of these tests show that the equipment tested meet the specifications of DO-142 Category A. Recent works had indicated that the interference susceptibility characteristics of ADF receivers may be dependent primarily on the absolute level of the undesired signal, and secondarly on the ration of the desired to the undesired signal. The data presented in this report, however, demonstrated that the interference characteristics of the aircraft ADF system are a funciton of the ratio of the desired to the undesired signal levels present at the antenna, and are not correlated to the absolute undesired signal levels.
