Abstract
A process for an electronically steerable parasitic array (ESPAR) antenna includes operating the ESPAR antenna with a receiver in Normal Mode until an internal flag is generated by the receiver indicating jamming RF noise preventing Normal Mode operation, causing the ESPAR antenna to switch to Anti-jam Mode. Anti-jam Mode includes a Search Mode and a Track Mode. The ESPAR antenna is steered in Search Mode, causing the ESPAR antenna to beam in a circular pattern to locate a spatial direction of the jamming RF noise, identify the spatial direction of the jamming RF noise preventing Normal Mode operation, and place a null in the spatial direction of the jamming RF noise. The ESPAR antenna switches to Track Mode to maintain the null in the spatial direction of the jamming RF noise until the jamming RF noise is not present. The ESPAR antenna then returns to operating in Normal Mode.
