Spectrum of the signal element at the output of the receiver of the equipment for probing the ionosphere

Application of model of mixture of probabilistic distributions for definition of the signals of radiophysical probing

Alexey A. Kolchev, A. E. Nedopekin


The article describes a model representation of radar probing data in form of a mixture of background and target samples, which is the sum of two random variables with very different parameters. For model development we research the behavior of the central moments of the distribution mix without assuming the distribution law form. An example it is described the detection of the signal at the output of compression system of chirp ionosonde.
