Web Abstract

High frequency ultra-low-noise amplifiers (ULNA) and receivers are complex and expensive. Therefore, any method that allows their efficient use is important. A new optical method presented recently allows using two sets of N-element ULNA receiver arrays to make N2 beams on the sky. This proposal aims to design, develop, demonstrate and deploy a novel radio telescope using this new optics. Once demonstrated, it will be useful for high frequency applications in radio-astronomy and in strategic areas such as meteorology, defence and space.

The instrument, first-of-its-kind, will have most parts indigenously built, satisfying the make-in-India paradigm. This includes development of X to Ku-band ULNA fitted to constant-aperture feeds, economical technology for telescope construction and sophisticated digital receivers. A key outcome will be an economical, imaging radio telescope, operating in X to Ku-band. The project will serve as a training ground for post-graduate students and researchers, thus befitting an MHRD supported project.
