Abstract
In an area 3 300 square degrees 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 were found, as well as three new rotating radio transients (RRATs). For new sources, their main characteristics are given. The dispersion measure of transient and pulse half-width are in the ranges of 7.2–59.9 pc/cm3 and 20–300 ms. 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.
