Caorsi, Salvatore and Massa, Andrea and Pastorino, Matteo and Randazzo, Andrea (2003) Synthesis of sum and difference patterns for monopulse antennas by an hybrid real/integer-coded differential evolution method. UNSPECIFIED. (In Press)
The synthesis of sum and difference patterns of monopulse antennas is considered in this paper. The synthesis problem is recast as an optimization problem by defining a suitable cost function based on the constraints on the side lobe levels. A subarray configuration is considered and the excitations of the difference pattern are approximately determined. The optimization problem is efficently solved by a differential evolution algorithm, wich is able to contemporarly handle real and integer unknowns. Numerical results are reported considering classic array configurations previusly assumed in the literature.
