Radar Antenna Sidelobe Reduction Techniques
We tend to obtain the angle estimate of the target, by transmitting a pulse towards the target and obtaining the echo in four different receivers. To achieve this we simulate a target and perform Digital Pulse Compression (DPC) and Doppler filtering, by forming eight filter banks, thus separating target from stationary clutter and to obtain monopulse sum and difference pattern, Digital Beam Forming (DBF) technique is followed.
Genetic Algorithm & other Optimization Techniques
Element failure in the active antenna array hamper the performance of the active antenna array. Optimization techniques like Genetic Algorithm, Particle swarm optimization, Iterative Fourier Transform are proposed for element failure mitigation in active antenna arrays. It is found that among all, PSO gives the best approximation in terms of Beam width and time taken to approximate.

FPGA Implementation of Error Detection and Correction for Space Application
Design and implementation of error detection and correction recommended by CCSDS. Combination of the two codes can be used to form concatenated codes with RS code through intermediate interleaving and an inner binary convolutional code which provide higher efficiency and coding gain.
RCS reduction of Canonical Targets using Genetic Algorithm systhesized RAM
A novel procedure for synthesizing radar absorbing materials(RAM) for RCS reduction in a wide band. Modal solutions are integrated into a GA optimization technique to obtain the best optimal composite coating.
