(Hopefully, the first of many entries on this subject)
Mandar is working to create a program which will replace a bulk of old, creaking machines at GMRT and other similar synthesis-imaging instruments, which produce a stream of cross-correlations between different antennas that are separated from each other by a huge distance.
The first (baby) steps are to create a program to compute cross-correlations from a stream of numbers. Then, we develop the same algorithm for an input of quantized numbers. After correcting for source delays (fringe-stopping and fractional delay correction), we compute an FFT of the cross-correlation series, to obtain the power spectrum of correlations. Finally, we tie this bit with astronomical source co-ordinates.
