ACCURATE DME FOR USE WITH ILS.

Abstract

This report evaluates the effect on the accuracy of DME, especially in the presence of echoes, of using pulses which rise more rapidly than the standard Tacan pulses without causing improper operation in the adjacent channels. Fruit and identification signals were found to affect the accuracy significantly and a study of these effects was added to the investigation. This report proposes an ILS-DME transponder capable of receiving and emitting sharply rising pulses. To obtain the maximum accuracy from the system, it is proposed to provide the airborne DME with the same capacity. The proposed airborne DME will operate also with currencly installed enroute transponders, and vice versa. (Author)
