New Patriot radar display improves situational awareness for operators

16 October 2018

Raytheon has upgraded the screen display for Patriot weapon system operators, adding three-dimensional (3D) color visuals and improving operators' situational awareness.

The Warfighter Machine Interface (WMI) takes the legacy Patriot display and moves it into the twenty-first century, Bob Kelley, a senior manager at Raytheon Integrated Defense Systems, told Jane's .Raytheon's WMI (R) is an upgrade to the legacy Patriot radar display (L), replacing the old 2D black-and-white visuals with an intuitive 3D colour screen.

The current Patriot display provides data in black and white and 2D. Operators have to memorise where information is stored among 100 tabs and they must scroll through the tabs to find precisely what they are looking for.

For example, to determine if an aircraft is flying at the proper altitude in a safe passage corridor (referred to in this instance as F770) the operator must find and open the tab where the data is saved. Then the operator has to scroll through all the information saved in that tab to find F770, which states that this particular safe passage corridor is set for 20,000 and 30,000 ft.

With WMI, operators need only to manipulate the image on the screen to see that the pilot is flying below the safe passage corridor altitude.

"It takes me about 35 or 40 seconds to figure that out on the old display, but about a second on the new display," said Kelley. "We worked with human systems engineering folks to make this as user friendly as possible."

Raytheon has also improved how operators receive Patriot health and status information. Kelley said operators want to be able to focus on the battlespace. Now a symbol, such as a flashing yellow light, appears on their main display, alerting them to an issue. Health and status data are displayed on a monitor above the battlespace display.
