Very-long-baseline interferometry (VLBI) application to detect objects in near and far space

July 20, 2021

From December 2020, Ventspils International Radio Astronomy Centre (VIRAC) is implementing the scientific project “The application of the forward scatter radar method for the detection of space objects”, No. lzp-2020 / 2-0101. The project researches, develops and evolves new radar methods with the aim of accurately determining the location positions of asteroids and comets approaching Earth.


One of the tasks of the project is to explore the application of a new and unique radar method based on radio wave scattering. This method is based on the applied effect that occurs when a bright celestial body illuminates the studied body, thus the energy is scattered along the line of sight forward, thus significantly increasing compared to the reflected energy. The developed method allows to detect space objects, regardless of its shape, material and radiation intensity. The “through-scattering” location method is implemented by combining radar VLBI technology and the scattering effect of electromagnetic radiation, involving bright space objects as transmitters in observations. By applying this method, the probability of detection of bodies that pose a threat to the Earth can be significantly increased, as well as the method allows to increase the observation distance at which the observation body would be identified.


During the last four months, VIRAC researchers have been working on the detection of space objects using the “through-scattering” location method, thus evaluating the effectiveness of the method in an experimental way. By July 2021, more than 15 experimental sessions were performed using the Irbene radio telescope complex in single station mode and interferometer mode. RT-32 and RT-16 VIRAC radio telescopes (using 32-meter and 16-meter parabolic antennas, respectively) and 1.6 GHz frequency band receivers were used in the experiments. In Figure No.1 the scheme of the experiment is displayed. The Global Navigation Satellite System (GNSS) GPS and Galileo satellites were used as radiation sources or transmitters in the experiments. During the experiments, using the “through-scattering” location method, observation lines “transmitter-receiver” (“transmitter” – a specific navigation satellite, “receiver” – Irbene radio telescopes) were created, thus space debris objects of different sizes were identified, as well as an International Space Station with a total geometric area of ​​approximately 400 m2.




Figures No. 2 and No. 3 show one of the results obtained using the interferometer mode and observing a large fragment of space debris while crossing the “transmitter-receiver” location line. Images are shifted sequentially at 30-second intervals. Figure No. 2 shows the result of the observation before the moment when the fragment of the space debris crosses the “transmitter-receiver” location line, but Figure No. 3 shows the signal obtained at the moment when the fragment passes over the “transmitter-receiver” location. The figures show the power spectra of the interferometer signal, on the x-axis – frequency (Hz), on the y-axis – time (s) and on the z-axis – power in relative units. Two signals can be clearly distinguished from the obtained results: a signal with a slowly changing frequency, which represents the radiation of the satellite, and a signal, the frequency of which changes rapidly over time, thus representing a fast-flying space debris object.




During the experiments, a successful treatment result was obtained in more than 50% of the object observations, observing debris with different geometric areas, at different distances from the Earth and at different angular distances from the location line. The analysis of the obtained results will allow to develop recommendations on how to choose the optimal observation mode for various objects, as well as will allow to develop a methodology for detection of space objects with radio location based on the effect of radio wave scattering.


The research is implemented within the Latvian Council of Science Fundamental and Applied Research Project No. lzp-2020 / 2-0101 “The application of the forward scatter radar method for the detection of space objects”.

VUAS adopts policy for equality, diversity and inclusion

By Rota Žagare • May 29, 2026
Ventspils University of Applied Sciences has officially adopted the COLOURS Alliance EDI Policy – a shared framework for equality, diversity and inclusion. The policy will now be adapted and implemented within the university’s operations. The aim is to strengthen inclusion across education, research, and everyday practices. The policy can therefore be seen as both a pedagogical and strategic implementation tool to prevent discrimination, increase understanding of differences, and equip students and staff to perform at their best in diverse teams. EDI stands for equality, diversity and inclusion. The training in EDI is designed to strengthen interpersonal relationships, raise awareness of the value of diversity in innovation, creativity and knowledge development, and encourage reflection on one’s own position and approach to others. The implementation of the policy contributes to the development of generic competences and critical thinking among both students and staff. This EDI policy is part of a much larger context, as we are one of nine higher education institutions in Europe adopting the same framework. EDI as a driver for an inclusive society The policy also emphasizes the importance of collaboration through the Quadruple Helix model, where universities, industry, the public sector, and civil society work together. The goal is not only to develop knowledge within EDI, but also to disseminate it and create societal impact. The policy marks the starting point for new initiatives and serves as a bridge to society. EDI strengthens the quality of education and research and is an important tool for both current operations and future needs. Signed policy is available HERE
