“…Before calculating the FFT, the data is multiplied by 18-bit coefficients of a window function of same length as the data segment. In order to save FPGA resources, a custom method involving two real sequences based on a single complex FFT is used (Vasilyev et al, 2014). This algorithm requires further data arrangement into channels, but the gain in processing time is much higher than the computational burden needed for data arrangement.…”

This paper describes digital radio astronomical receivers used for decameter and meter wavelength observations. Since 1998, digitals receivers performing on-the-fly dynamic spectrum calculations or waveform data recording without data loss have been used at the UTR-2 radio telescope, the URAN VLBI system, and the GURT new generation radio telescope. Here we detail these receivers developed for operation in the strong interference environment that prevails in the decameter wavelength range. Data collected with these receivers allowed us to discover numerous radio astronomical objects and phenomena at low frequencies, a summary of which is also presented.

“…For receiving and postprocessing signals each GURT subarray is equipped with a wideband digital receiver (Advanced Digital Receiver, Fig. 2b) [Vasilyev et al, 2014]. The receiver parameters are well matched with the parameters of the GURT subarray and allow us to receive the cosmic signals in whole frequency band (from 8 to 80 MHz) with high time-frequency resolution and high dynamic range.…”

The 12-th Workshop "Solar Influences on the Magnetosphere, Ionosphere and Atmosphere" was scheduled to be held from June 3 to 7, 2020 in Primorsko, Bulgaria. Due to the coronavirus pandemic, the Local Organizing Committee decided to postpone the workshop until September. Unfortunately, in September the situation was not better, and it was not possible to hold a face-to-face meeting. Therefore, the workshop was held online. 24 papers with a total of 76 authors from 11 countries are included in these Proceedings.
