Decimetric (1.2 - 1.7) GHz radioheliograph, hence afterward referred as BDA, is planned by the Astrophysics Group of the INPE as a multi-institutional and collaborative program with India, for investigations of solar and non - solar phenomena. Simultaneous images obtained of the solar phenomenon in X-rays over a wide energy range and decimeter wavelength will lead to better understanding of the particle accelerations in the solar flares. In the first phase the Radioheliograph will be T shaped array 256 meter by 144 meter consisting of 26 parabolic dishes of 4 meter diameter, 17 along the east west arm and 9 along the south arm, each separated by 16 meter and will be situated at longitude 22.7 south and latitude 44.9 west in the town known as Cachoeira Paulista. The final version of the BDA will be an interferometer array with 32 parabolic antennas of 4 meter diameter with east -west base line of 2560 m and compact T shaped array at the center of this base line as mentioned above. Thus, final attainable spatial resolution will be 18 x 24 arc - seconds. The images will be obtained in snapshot mode with time resolution of 100 ms, initially at 1500 GHz. Actual status of the development, planned system and images obtained with different combinations of spacing of the antennas using Nobeyamas data as input has been presented and compared with images obtained with Nobeyama Radiolheliograph and X-ray images obtained by YOHKOH satellite.
