Abstract : The report covers the results of laboratory and field tests of various TACAN ground station modifications designed to minimize the false DME problem. An airborne and ground data collection package was designed to record the percentage of false replies synchronous with an aircraft interrogation. The modifications tested included a modified GRN-9 TACAN receiver, a tighter decoder tolerance modification (Tulsa modification), a jittering dead time gate, and a retriggerable long dead time gate (Crazy Woman modification).
