FIELD: the invention refers to hydrolocation and may be used at creation of a system of detection of fishing boats in a protected sea economical zone or a system of protection of oil production platforms from icebergs.
SUBSTANCE: the mode of detection of a signal of noise emanation of sea objects envisages reception of mixture of proposed signals and interferences, measurement of the spectrums of the received mixture of the proposed signals in each of totality of directions of observation, measurement of an angular position of each locality in space maximum on each spectral component of the results of the measurement of spectrums, formation of evaluation of generalized coordinate diagram for each indicative direction of observation and each spectral component, functional transformation of evaluations of the generalized coordinate and forming marks on the results of the mentioned functional transformation.
EFFECT: increases noise immunity of detection of noise emanation of sea objects.
