The current state of research on microwave subsecond pulses (SSPs) based on observations of radio-frequency radiation from solar flares with high temporal, spatial, and spectral resolutions is reviewed. It is shown that knowledge about the localization of SSP sources in the flare region, available with the help of large radio interferometers, radically affects the understanding of the nature of SSPs. Based on the unique observational material accumulated in radio observations over the past 30 years, the characteristics of SSPs have been studied, they have been classified according to their spectral characteristics, and the mechanisms of their generation have been determined.
