| Abstract: | This paper discusses the application of Rician Distribution multipath descent in two kinds of conventional direction-finding. According to the special demand for SNR of the conventional direction-finding technology, an affection analyses of Rician Distribution multipath descent channel to amplitude-compare and phase-compare direction-finding error is given. The error dithering distribution is deduced, and a simulation is given to show the restriction of the distribution function. In the end, some engineering problems of interest, such as model parameters estimation, sampling number, are discussed. |
