Sinuous Spiral Antenna for ANA/ALQ211 (SIRFC) EW System (Special Operations Command
Abstract
This validation project will test and evaluate a new detection antenna for the ALQ-211 Suite of Integrated Radio Frequency Countermeasures (SIRFC) currently being fielded on the MH-47G and CV-22. The primary outputs and efficiencies are as follows: the new antenna provides polarization sensitivity allowing SIRFC to better correlate the received signal with its order of battle database, which leads to quicker identification and jamming. Simulation and lab testing will be performed to validate that sinuous antenna face conforms to the spiral antenna located within the AN/ALQ-211 Quadrature Antenna Assembly. Prototype antennas will be measured and analyzed for performance against defined polarizations. In addition the prototype antennas will be measured, analyzed, and evaluated for performance against legacy spiral antennas. RDT&E cost avoidance was projected to be $10.000 million, and procurement cost avoidance was valued at $3.000 million. Project completion is scheduled for August 2010.
