Abstract:

Partial results of an experimental program to determine the electromagnetic noise environment at UHF on board an aircraft are presented. Contributors to an airborne receiver noise temperature including galactic noise, earth temperature, P-static, atmospherics and industrial noise were measured and are discussed. A model of the industrial noise is presented whereby the industrial area is considered as a uniformly distributed source of independent radiators, the magnitude being the same for all cities measured with the exception of the New York City area. RFI generated by on-board equipment andor ground transmitters will be covered in a subsequent report.
