Array Design Using Genetic Algorithm for the Generation of Sum and Difference Patterns

In the field of pattern synthesis, design arrays to synthesis optimized sum and difference patterns in a successive manner is an important problem most radars. Although several researchers published many papers open literature, investigations are made by authors discrete radiators using well-formulated Genetic Algorithm (GA). The practical constraints taken into account amplitude distribution produce with desired side lobe levels without broadening main beam. Such found be very useful high-resolution radars where EMI problems also addressed. IFF radars, both extremely distinguish between friendly aircraft enemy aircraft. conventionally produced involving two antennas. One directional antenna another omnidirectional antenna. However, present work, they generated only one deep null boresight direction lobes high slope antiphase excitation one-half array.
