  • A low cost steerable radio-telescope 
    Sawant, H. S; Neri, J. A. C. F; Fernandes, F. C. R; Cecatto, J. R; Sankararaman, M. R; Faria, C; Stephany, S; Rosa, R. R; Andrade, M. C; Alonso, E. M. B; Ludke, E; Subramanian, K. R; Ramesh, R; Sundararajan, M. S; Ananthakrishnan, S; Swarup, G; Boas, J. W. V; Botti, L. C. L; Moron, C. E; Saito, J. H (Elsevier B. V., 2003)
    We present the technical characteristics of a low-cost radio telescope for solar/non solar observations at decimetric (1200–1700 MHz) and centimetric (2700 and 5000 MHz) wavelengths known as Brazilian Decimetric Array ...
  • Multi-station observations of interplanetary scintillations 
    Ananthakrishnan, S; Kaufman, J. J (Astronomical Society of India, 1982-03)
    Solar wind velocity estimation using the method of multi-station interplanetary scintillation observations has been reviewed. It is shown that the interred model for the electron density fluctuations in the solar wind ...
  • On the nature of compact components of radio sources at 327 MHz 
    Balasubramanian, V; Janardhan, P; Ananthakrishnan, S; Srivatsan, R (Astronomical Society of India, 1996)
    The interplanetary scintillation (IPS) survey of about 5000 radio sources carried out during 1992-93 with the Ooty Radio Telescope (ORT) at 327 MHz has resulted in the detection of compact components in about 2700 sources. ...
  • Solar physics using the Giant Metrewave Radio Telescope 
    Ananthakrishnan, S (Astronomical Society of India, 1998)
  • Southern hemisphere solar radio heliograph 
    Sawant, H. S; Fernandes, F. C. R; Neri, J. A. C. F; Cecatto, J. R; Faria, C; Stephany, S; Rosa, R. R; Andrade, M. C; Ludke, E; Subramanian, K. R; Ramesh, R; Sundrarajan, M. S; Sankararaman, M. R; Ananthakrishnan, S; Swarup, G; Boas, J. W. V; Botti, L. C. L; Moron, C. E; Saito, J. H; Karlicky, M (European Space Agency, 2002-12)
    The Brazilian Decimetric Array (BDA) is being developed at National Institute for Space Research (INPE) as an international collaborative program. Initially, the BDA will operate in the tuneable frequency range of 1.2-1.7 ...
