VHF-LB SDR Phased Array Jamming Resistant Antenna

Genetic algorithm for optimization of beam forming in linear array antenna is used. The goal is to achieve a -30 dB null depth in pattern, with null steering capability over the frequency band. The simulation result is -85 dB that the SuperNEC results accepted this result by -56 dB null depth. Software define radio (SDR) technology and digital I/Q modulator are used to implement the system
