Broadly, Chandra’s research looks at dual-polarization technology, solid-state transmitters for weather radars, small X-band frequency radars, and polarimetric phases array radars. Through the extensive research done in all these areas, his lab has been able to make solid-state transmitters a mainstream and “industry accepted” concept for weather radar development. Further, his dual-polarization technologies have enabled weather radars to use higher attenuation X-band frequencies, allowing them to become physically smaller and less expensive. Currently, the lab is focusing on developing new technologies to combat issues related to AESA antennas and their ability to change their polarimetric characteristics for their potential incorporation into phased array weather radars.
