Northrop delivers CEESIM to Saab

Northrop Grumman has delivered a Combat Electromagnetic Environment Simulator (CEESIM) to Saab, the company announced on 22 March.

The simulator will be used for aircraft testing on Saab's Gripen JAS 39 multi-role fighter.

CEESIM provides RF simulation of multiple, simultaneous emitters and static/dynamic platform attributes to simulate battlefield conditions to test and evaluate the effectiveness of electronic warfare equipment.

The CEESIM system includes the advanced pulse generation (APG) capability, which uses the latest digital technology to generate advanced waveforms. It also has the ability to perform digital modelling of multiple active electronically scanned array antennas.

Joe Downie, site director of Northrop Grumman's Buffalo-based Amherst Systems, said: 'CEESIM's high-speed direct digital synthesizer technology brings significant advantages to Saab, including higher modulation sample rates, wide bandwidth precision intrapulse modulation, higher frequency resolution and accuracy, and reduced calibration time.

'The APG utilizes a modular design for improved maintainability. All of this leads to lower cost and increased system reliability.'

This is the first time the company has delivered a CEESIM system with APG technology.
