Radio astronomy has been a cornerstone of space science and astrophysics, enabling the exploration of the universe through non-optical electromagnetic signatures. With the rapid advancement of wideband antennas, low-noise front-ends, reconfigurable systems, and intelligent signal processing, the field is entering a transformative era. This special session aims to bring together researchers, scientists, and engineers to discuss cutting-edge developments in radio astronomy instrumentation, signal analysis, space-based interferometry, and their allied technologies. The session will emphasize the integration of advanced antenna systems, digital back-end processing, and space communication techniques that enhance the sensitivity, resolution, and efficiency of modern observatories. It also aims to highlight the synergy between space communication and astronomy through shared technologies such as phased arrays, beam steering, calibration algorithms, and cryogenic receivers. This special session will provide a collaborative platform for academia, research institutes, and space agencies to exchange ideas and envision the future of radio astronomy and its allied disciplines.

The advancements in radio astronomy are not limited to astrophysical observations but extend into the domains of advanced communication, sensing, and electromagnetic system design. Many of the innovations in receiver chains, beamforming, and array calibration have direct implications for modern satellite and deep-space networks. This session bridges the gap between radio astronomy and space communication engineering, promoting cross-disciplinary collaboration essential for next-generation missions such as lunar radio observatories, deepspace interferometers, and adaptive space telescopes
