 Ongoing/Completed Research Project 
[1] Project Title: Design and development of Harmonics RADAR system for tracking of pollinators  
Brief of project: This project is about development of the harmonics radar System for tracking of pollinators which is subject interest of Microwave Engineering.  The harmonic radar system is a multi-static radar system with a mobile receiver flown with UAV for tracking of target. A stationary radar transmitter provides power to the tags which is attached with insects for tracking. The tags are highly miniaturized meta-material resonant antennas along with frequency double circuit that receive and respond at fundamental and harmonics frequency.  We have produced the smallest, lightest harmonic radar tags on record (2.8 x 2.8 x 0.7mm); designed and built a light, ultra-sensitive receiver to mount on the UAV; and produced a filtering system for a commercial 3.0kW radar transmitter to eliminate the undesirable harmonics.
