746 Test Squadron Multi-Element Antenna Wavefront Simulator with Embedded Jammers

Matt Alsleben and Larry Smith

Abstract:	"Navigation Warfare (NAVWAR) studies identified the need to enhance the anti-jam capability of User Equipment being designed for US and Allied Uniformed Services. The use of multi-element antennas, or Controlled Radiation Pattern Antennas (CRPA), is becoming increasingly popular for anti-jam Global Positioning System (GPS) protection. New CRPA designs implement the use of digital technology in the Antenna Electronics (AE) unit. To adequately test the CRPAÕs overall effect on system performance, the entire navigation system, including the multi-element CRPA, the antenna electronics unit, and the GPS receiver must be evaluated. Proper CRPA simulation requires numerous interference signals to be incorporated with GPS signals into a precise wavefront, appropriately phased for arrival at a spatially diverse adaptive antenna electronics unit. To meet these new test requirements, the 746 TS is developing a laboratory test capability for evaluating GPS navigation systems equipped with a controlled reception pattern antenna and antenna electronics unit. This development will allow the 746 TS to dynamically simulate a wavefront of multiple jammers and GPS signals to the AE."
