Unified field of detection probabilities for heterogeneous means of observations

The problem of calculating a single detection probability field for stationary and moving observers controlling a given region and working in a passive mode in different frequency ranges is considered. Currently, the implementation of the ideas of "network-centrism" in relation to solving the problems of searching for a marine underwater object leads to the integration of underwater surveillance systems and to the integration of all available positional and maneuvering sonar systems into a single complex of underwater observation, in which the results of the work of heterogeneous means of observations could be combined. In this work we consider stationary sonar station located on a plane equipped with the Cartesian coordinate system XOY, whose coordinates are known, and calculate a single object detection probability field for all stationary sonar station throughout the region Р _det(x, y). This field is used as the basis for the integration of underwater observation systems and for combining all available positional and maneuvering sonar systems into a single underwater observation complex, including when operating in an anisotropic environment. All the examples cited were calculated using the MATLAB computing environment. The presence of a single field of probability of detection for a given area: - firstly, it greatly facilitates the work of the operator; - secondly, it allows you to quickly make adjustments to the work of maneuvering means; - thirdly, take into account data from non-acoustic physical fields in this single field of probability.
