Abstract :
It is well-known that the problem of radio direction finding (RDF) appears in various shortwave systems in the case of multipath signal propagation. Direction-finding algorithm development has been facilitated with the invention and widespread usage of phased-array radars. However, RDF problem has not been solved yet, because of various limitations imposed on formulations and solutions in developed algorithms (e.g, the waveform of detected signal is assumed to be known). This article provides new recurrent algorithm with super resolution properties, based on adaptive Bayesian approach, which works in the case, when there is no any priory information about a waveform of the received signal.
