An active acoustic technique for monitoring the whales is proposed. The technique allows one to monitor the whales' crossing of a conventional borderline extending for several tens of kilometers in a shallow-water area. The potentialities of the technique are demonstrated in the framework of a numerical experiment by solving the problem of diffraction by model scatterers in an acoustic waveguide. The scatterers are selected in the form of soft spheroids with dimensions characteristic of various kinds of cetaceans.
