Algorithms for the earth's surface imaging in the ranges of angles from 20° to 50° and from 0° to 20° to the right and left to the nadir have been synthesized. Based on the two obtained algorithms, a block diagram of the complex has been developed. The results of the developed complex simulation are given. The results of experimental studies on the presence of correlation between wideband signals are presented.

Aerospace Wide Swath Radio Vision Complex

The goal of the project is to construct an Affordable Small Radio Telescope (ASRT) that will allow students to participate in radio astronomy. With components from Direct-to-Home (DTH) satellite systems operating in the radio frequency (RF) framework, the ASRT offers a user-friendly platform for astronomical observations, with a special emphasis on solar studies. With the help of low-noise block converters (LNBs) and parabolic dish antennas, the ASRT provides students with an inexpensive way to investigate radio astronomy methods. The project places a strong emphasis on experiential learning by letting students assemble and use the telescope under supervision. Students’ comprehension of signal capture and processing is improved by the ASRT by utilising the concepts of RF engineering and analogue communication. Through the use of the ASRT, students can conduct solar observations that provide insights into solar variability and phenomena. Overall, the ASRT project contributes to advancing education in both radio astronomy and engineering, fostering interest in scientific exploration and providing a valuable learning experience for students.

Affordable Small Radio Telescope (ASRT) for Solar Observation

Cutting edge astrophysical studies require more and more observing time at low-frequency radio telescopes, which is limited and quite expensive. Modern digital signal processing systems still unable to provide affordable computational and storage resources to allow simultaneous beamforming in a wide frequency range for multiple studies. Low-frequency radio telescopes of a new generation are very flexible and could be split into subarrays or groups of subarrays for some studies which do not require large antenna effective area and high directivity. In this paper we make a survey of astrophysical studies in the frequency range 8–80 MHz using a rather small part of the low-frequency radio telescope GURT - the subarray of 25 active antennas.
