Communicating Through Jammed Environments
Harris uses its unrivaled interference cancellation technology to remove the jammer interference and protect the aircraft’s communications.
The powerful ALQ-99 Tactical Jammer Systems have been an integral part of the Navy and Marine Corps Electronic Attack communities since the introduction of the EA-6B Prowler. The ALQ-99 jammers are currently carried on the EA-18G Growler and the USMC EA-6B Prowler. Although very effective in blocking enemy radar and communications, they could also interfere with the aircraft’s onboard radios.
When the Prowler Electronic Countermeasures Officer (ECMO) turned on the jammers, their radio communications were often blocked by the high energy produced by the ALQ-99. They found they could no longer receive updated information from friendly forces, resulting in lost tactical flexibility and increased risk to safety of flight.
Prowlers would fly pre-planned missions, and if someone needed to contact them in a jamming environment, the strike package would include an additional aircraft flying next to them to relay changes to the plan or any safety of flight issues.
Even in close proximity, the jamming energy was powerful enough that they still could not communicate over the radios and often resorted to hand signals and writing on grease boards during the day and flashing lights at night.
As the Growler aircraft was developed to replace the Prowler, the Harris INCANS (INterference CANcellation System) solved this problem. The groundbreaking interference cancellation technology in INCANS removed the jammer interference, restoring the ability of the EA-18G pilot and EWO (Electronic Warfare Officer) to communicate with friendly forces and respond quickly to the changing tactical environment.
