Semi-automated Rotman lens design focusing on anti-jam performance

In this paper, the authors introduce the need for semi-automating the design of Rotman lenses and describe steps taken at SPAWAR Systems Center Pacific (SSC-PAC) to address this need. With this semi-automated design tool, the authors have been able to design several different lenses and not only verify their individual performance but compare key traits such as phase/magnitude error and insertion loss amongst all the lenses and against some lenses reported in the literature. These traits are important in improving antijam/interference performance of a Rotman lens-based wireless communications system.
