EVALUATION OF TACAN CW INTERFERENCE MODIFICATION.

Abstract

The report presents the results of laboratory and field tests of a NAFEC-developed modification designed to alleviate the CW interference problems that have been suspected of causing outages of GRN-9 and RTB-2 TACAN (transponder) ground systems. Previous investigation concluded that the level of spurious RF CW, radiated by certain airborne interrogators tested, was of sufficient magnitude to cause transfer or shutdown of TACAN equipment used for air navigation when located near taxiways and/or runways of airports. The modification was field-evaluated at four commissioned facility sites and was found successful in preventing equipment transfers or shutdowns of TACAN at ground facilities caused by CW interference.
