Evaluating the stealth performace of complex targets in general and the transient and dynamic RCS of chaff payloads in particular is the first reserch objective of my group. For chaff, this leads to improved chaff design and indigenouisation of the production thereby. Also, development for broadband radar absorbing material for airborne and naval applications is attempted by the group.
Perfecting the GPR as a tool for various mining, civilian, agricultural, structural, security as well as other civilian application is the second research objective of my group. This includes improved antenna design, improved pulse generator design, improvement of calibration methodology, improved system modeling, improved detection strategy for hybrid structures made of conductor and dielectrics etc.
Perfecting the high power microwave technology is the third research objective of my group. This includes improvement in sensor design, improvement in antenna feed design, improvement in canonical target identification strategy detection strategy etc.
In cellular telephony and also in many other areas where frequency allocation is done, presently statistical or empirical models are followed. This is the reason for high drop rate. To solve the problem, development of deterministic and ray based models is the fourth research area of my group.
For predicting atmospheric losses during satellite communication, some propagation models are used which are not developed from the experience of Indian tropical region. One such model development is the fifth research goal of our group.
