The paper is devoted to the modernization of the previously developed algorithm for detecting pulses in geoacoustic signals against a background of noise. The algorithm is implemented as a computer program. Geoacoustic signals are recorded in Mikizha Lake in Kamchatka using a combined receiver. The receiver simultaneously records acoustic pressure and three orthogonal components of its gradient at a point in the medium. From the registered signals, an input data series is formed in various ways for further processing by the program. The paper proposes a new way of forming the input series based on the Umov–Poynting vector. The improved algorithm detects hundreds of times more pulses in highly noisy signals. This increases the accuracy of determining the direction to their sources. Detailed histograms of the spatial location of geoacoustic emission sources are constructed. Note that the algorithm can be applied to pulsed acoustic signals only if they are registered by a combined receiver, i.e, the values of pressure and its gradient at the point of the medium under study must be known simultaneously.
