Abstract
Navy SIGINT systems are required to receive low level signals in the HF, VHF and UHF frequency bands. The SINCGARS (30-88 MHz) band occupies part of the VHF frequency band where signal reception is required. U.S. Navy ships will have from 2 to 8 SINCGARS transmitters installed, which are used to communicate with shore operational units. SINCGARS (Single Channel Ground and Airborne Radio System) radios use a frequency hopping signal to prevent jamming and interception, which is difficult to remove and prevent electromagnetic interference to the SIGINT receivers. GIRD Systems has developed an innovative approach that is capable of mitigating such SINCGARS interference without needing a copy of the interfering signal. The proposed approach will meet the space and volume requirements.
