Abstract

In an area of 3300 sq. deg, a search for pulse dispersed signals using a neural network has been carried out. When processing observations over an interval of six months, the pulses of fifteen known pulsars, as well as three new rotating radio transients (RRATs), have been found. For new sources, their main characteristics have been provided. The dispersion measure of transient and pulse half-width are in the ranges of 7.2‒59.9 pc/cm3 and 20–300 ms, respectively. An RRAT search scheme has been developed to detect pulses with a signal-to-noise ratio (S/N) below the threshold required for reliable detection.
