Abstract :
A direction finding architecture that implements an innovative number system encoding of phase samples, the robust symmetric number system (RSNS), is described. The RSNS possesses Gray code properties and provides significant advantages over conventional phase scanning methods and other symmetric number system encoding techniques. The design equations for a RSNS array are presented. Simulation results for a prototype RSNS array are shown, and its performance compared to previously published results for other number system encoded direction finding architectures
