Frequency Hopper/DSSS Detection

"Advances in spread spectrum communications systems have provided military and other users with readily available low-probability-of-intercept transceivers for secure, clandestine communications. The use of these systems may constitute a threat to SpecialOperations Forces. These forces need a system to detect, identify, locate, and copy modern LPI communication emitters to counter this threat. The system must be capable of deployment with ground forces, in maritime operations, in a support role onaircraft, or left behind for remote operation. Radix proposes to design an effective search system for threat LPI emitters to satisfy this need in a rugged, low power, small form factor, 100% COTS hardware architecture. The proposed system architectureuses the DRT receiver family. Radix algorithms, which have successfully operated against LPI signals on other programs, are integrated on COTS hardware processing nodes in a flexible, reconfigurable firmware/software design compatible with the JCAF. Theprocessing nodes are specifically structured to expedite upgrades for signal variants or new signal types, to be scaleable by adding additional nodes in a larger receiver configuration, and to take advantage of technology upgrades as higher capacityprogrammable devices and faster processors become available. The primary opportunity for this technology is initially with the US military. Since the processing is sophisticated enough to allow o
