Abstract Features receiving parametric array happen to in work, working in wave-guide with dispersion of sound speed. It is shown that change the frequency of the pumping waves changes form beam pattern that can serve by sign in ecological monitoring water area. The Reception parametric antenna presents itself array of the running wave, in which change to phase velocity of the wave of the pumping in consequence of dispersion in such antenna will bring about change the feature to directivities such antenna in the same way, either as in array of radio range. In this paper are brought structured schemes to realization of the receiving parametric array with different feature.
