The paper considers the parameter detection-and-measuring problem for a multielement target against the backgrounds of the nongaussian noise. A multielement target can serve as a signal acquisition simulation in a multipath channel due to re-reflection from the underlying terrain (land, sea) or elevated inversion tropospheric layers. The correlated nongaussian noise is described by the Markovian process with the given densities of the transition probabilities and the unconditional density of distribution. This pattern is typical for the noise due to the reflection from water surface, vegetated areas, elevated inversion layers in the troposphere, when the radar resolution cell is smaller than the representative scale of the surface inhomogeneities, e.g. the sea wave length. An exploratory model is suggested for the interference effects in the propagation channel. The number of sources and their characteristics are determined on the basis of the Fisher criterion for the significance estimation of signal source number.
