Direction finding with a rotating antenna

Abstract

Finding the direction of the emitters is a problem to be solved in many areas. One of the methods used for that purpose is that using a rotating directional antenna and obtaining the direction estimate by processing the measured signal amplitudes. Direction estimation, in principle, is based on the own antenna pattern modulation on the measured signal. In the paper, direction estimates of one or more emitters are found with two different methods (matched filtering and Wiener deconvolution), and performances (signal-to-noise ratio, changing emitter power, etc.) of these methods are studied.
