BUFFALO, N.Y. U.S. Navy officials at NAWCWD Point Mugu took delivery of Northrop Grumman's multispectral testing solution that recreates accurate mission-like conditions in the laboratory and on the range for the F-35 aircraft.

The testing environment consists of Northrop Grumman’s Combat Electromagnetic Environment Simulator (CEESIM), Signal Measurement System (SMS) and other stimulators, all under control of the Synchronizer Controller System (SCS). At the center of the environment is the CEESIM, which simulates multiple, simultaneous RF emitters as well as static and dynamic platform attributes to faithfully model true-to-war conditions. CEESIM’s Advanced Pulse Generation high speed direct digital synthesizer technology is used to generate realistic electronic warfare mission scenarios.

The SMS provides wide bandwidth signal measurement, recording and analysis capability which is used to validate the test environment and evaluate the system under test performance.

The SCS provides the tools to program an integrated multispectral test scenario, including threat radars, communications signals, radar and EO/IR signatures. The SCS also manages the execution of the scenario by all of the stimulators to ensure a coherent multispectral test environment.

“Keeping the F-35’s systems ready requires a fully integrated test environment like we have developed with CEESIM, SMS and SCS,” says Joe Downie, director, land and avionics C4ISR division, Northrop Grumman Mission Systems. “These systems work together to provide the environment complexity and density, measurement and analysis capability, and test control capability necessary to evaluate the F-35 in a realistic mission scenario.”
