I.J. Gupta works on antenna systems and signal processing methods for figuring out the direction a radio signal is coming from (direction-of-arrival estimation), including applications to GPS/GNSS receivers and radar. This involves designing and calibrating antenna arrays and developing mathematical techniques to improve the accuracy of locating signal sources, especially when signals are weak, overlapping, or the antenna behaves imperfectly.
