A Non-uniform DFT-based Batch Acquisition Method for Enhanced DME (eDME) Carrier Phase: Concept, Simulations, and Flight Test Results

K. Li and W. Pelgrum

Abstract: This paper proposes a novel batch acquisition method for eDME Carrier Phase based on non-uniform DFT. The theoretical false acquisition, failed acquisition, and wrong acquisition upper bounds are derived analytically and validated by Monte Carlo simulations. Actual flight test data recordings suggest the existence of substantial RF interference. Two algorithms are proposed to mitigate this interference. The resulting acquisition performance shows zero false and wrong acquisition and a very acceptable failed acquisition rate for the entire flight test.
