TTNT is a new operational technology being installed into the Multifunctional Informational Information Distribution System/Joint Tactical Radio System (MIDS/JTRS) unit, which operates across the 1300-2100 MHz band being installed on the EA-18G aircraft. During a typical jamming mission, the TTNT unit (upper/lower antennas) operation will receive interference from the on-board jammer units. This interference will not allow the EA-18G to receive external TTNT units. GIRD Systems proposes an innovative mitigation solution which will allow the TTNT to operate fully while in the presence of the interference.
Benefit: Simultaneous, co-located operation of communications equipment, sensitive receive systems, and electronic attack systems has been an ongoing problem for the military for many years. Similar problems also exist in the private commercial sector where electronic attack is unintentionally delivered by other communication signals which could be nearby. This is especially prominent when the FCC recently has been auctioning some frequency bands to secondary users, potentially causing significant EM interference in many previously clean bands. When the program objectives for this SBIR are achieved, the cosite interference mitigation techniques and products developed will be suitable for a wide range of customers, such as aviation and satellite communications.
