FIELD: physics.
SUBSTANCE: each system, based on its own quality criteria, independently performs frequency-time processing of a signal to generate a unique beam fan and a unique information array. In order to integrate systems without losing detection potential, a base system with the best resolution in the angular direction in the horizontal plane is chosen. Indicator arrays of the rest of the systems are reduced to the size of the indicator array of the base system by interpolating data between readings. The indicator arrays of all systems are displayed on a common indicator with a common axis of the angular direction in a common field of view. A noisy object is detected and information on the properties its signal is obtained based on the presence of local maxima on one angular direction in the set of systems. Interpolation of indicator arrays between readings, which is necessary for operation with indicators with raster graphics, is carried out, for example, via low-pass filtering after spatial Fourier transform.
EFFECT: enabling integration of any number of detection systems having different static beam fans and different detection potential, ie enabling integration of systems operating using different antennae and performing independent frequency-time information processing; for the integrated system, enabling signal detection at a pre-threshold level and obtaining information on frequency and time characteristics of the signal of a noisy object on the sea, which can be detected in the set of the systems being integrated.
