Abstract : The report covers the testing of two low-powered Distance Measuring Equipment (DME). The laboratory tests dealt with the effects of continuous wave (CW) interference on reply delay, receiver sensitivity, and squitter rate; the effect of various squitter rates on airborne interrogators, the effect of various interrogation levels on receiver delay, and the effects of various transmitted pulse parameters on the pulse pair spectrum. The flight tests identified the coverage area provided by a 90-watt DME ground station to various commercial and general aviation type DME interrogators. (Author)
