Institute of Radio Astronomy of NAS of Ukraine popup.description2 We observed a large sample of extragalactic radio sources using an advanced measurement and calibration technique developed for the URAN interferometers, and determined their angular structure at decameter wavelengths and its difference in the model approximation from high-frequency images. Spectra of model components in a wide frequency range and causes of their distortion have been determined, and physical parameters of the investigated objects are established. We studied a complete sample of the short-period pulsars (with respect to the selected criteria), a shape of their spectra was established, and the scattering angles were measured at decameter waves. A short-baseline interferometer was created using the UTP-2 sections as individual antennas and a simplified procedure was developed for measuring the angular dimensions of extended sources. The parameters of the solar corona have been measured. A technique and software for using the DSPZ receivers in interferometer studies with a significantly extended bandwidth was developed to increase a coverage of the uv plane and sensitivity of the measurements. An equipment and software for automation and remote control of the URAN radio telescopes have been created.
