Reconfigurable array antennas with side lobe level control by genetic modulation

In this paper the design problem of an equi-spaced linear array is considered with the constraint of reducing side lobe level which results in the leakage of the received signal energy. In order to achieve this, powerful tool based on the event of probability has to be chosen. We consider an evolutionary approach, which avoids the adaptive nature and avails the tuning mechanism. Genetic Algorithm which follows the nature dependent rules is used to achieve this purpose. The process of varying the characteristic parameter in the genetic optimization is termed as genetic modulation. In this paper the parameter of importance, is the mutation rate. The effectiveness of this variation, rule the design of linear array is shown by simulation results.
