DEVICE joint detection and estimation of signals of low-flying targets at the background interference and in multipath

摘要

Apparatus joint detection and estimation of low flying targets signals against interference and multipath conditions, having four parallel channels, which is input to a random process, characterized by a known fact that instead of the optimum receivers designed for optimal processing Gaussian signal in Gaussian noise and the noise , the device comprises sixteen receivers optimal OPi, j, decide that the signal detection task i-th type background noise j-th type, where i, j = 1, ..., 4, acc Corollary to a necessary and sufficient amount distributions analyzed: 1) Gaussian, 2) Weibull, 3) log-normal. 4) m-type; signals from the outputs of which are applied to the inputs of the decision unit, wherein selects the greatest of the output signals corresponding to the logarithms of the likelihood ratio unit and the full resolution signal, performing direct allocation signal reflected from the target to background antipodes.
