An Asynchronous SINCGARS (Single Channel Ground and Airborne Radio System) Frequency Hopping Notch Filter Based on Canceller Technology
Agency / Branch:
DOD / NAVY
Zeger-Abrams proposes to implement a SINCGARS RFI cancellation system to prevent the RFI from overdriving and desensitizing each of the four RF inputs of a cosite sensitive signal exploitation receiver. A unique feature of ZA's cancellation system is that it requires no input cables carrying RFI reference signals. Based on ZA's Phase I experiments, the SINCGARS RFI cancellation system is expected to produce >50 dB of RFI suppression with low impact on receiver noise figure. The system packaging will be modular, allowing straightforward reconfiguration for other applications.
