Abstract

Abstract

This paper deals with the influence induced by multipath propagation and optimal selection of M/N when frequency diversity technique is used. To ensure the detection statistic and choose the correct M and N, it must be known that the probability density function (PDF) of the noise plus target times the multipath factor. Differ from other papers, the more general model of reflection is adopt, the PDF is derived for a nonfluctuating target and for a Rayleigh target, then the relation between M/N and P_D/P_F is got by multi-pulse detection in multipath. (compared with free-space).
