Radiofrequency (RF) & Microwave remote sensing (MRS)

Radiofrequency (RF) & Microwave remote sensing (MRS) is a collective technique that involves the creation of electromagnetic (EM) waves, propagation of EM wave by radiation or transmission, reception of EM wave by means of scattering or reflection, and analyzing the information collected by the RF sensors in a meaningful way. The MRS is all about designing and using passive and active microwave devices to collect data related to the physical properties of natural and artificial media interacting with the EM waves.

Since microwave signals are sensitive to moisture in the soil, the MRS is preferred to study the vegetation and snow content in a large landscape. We study, design, and measure several passive and active devices e.g., antennas, radiometers, scatterometers, transceivers, and RADARs. The raw data collected as the backscattered electromagnetic radiation are analyzed and judiciously processed to provide information about the size, shape, and electrical properties of the surfaces or objects illuminated.

At the moment, the RF & Microwave team is working on establishing a central facility of remote sensing at IIT Tirupati under positioning and precision technologies for monitoring and analyzing spatially and temporally distributed resources.

This young group of RF and Microwave at TIH Tirupati has four members who share rich experience in RF and Microwave research.
