Northrop upgrades electronic warfare simulator

Northrop Grumman has completed performance testing on its Advanced Pulse Generator (APG), a next-generation upgrade for the company’s Combat Electromagnetic Environment Simulator (CEESIM) product used to assess electronic warfare equipment.

The CEESIM is designed to simulate complex, real-life electromagnetic warfare conditions such as angle-of-arrival radio frequency simulations, according to Northrop Grumman. It equipped with High Fidelity Intrapulse Modulation (HFIM) capability, which allows it to replicate the environments of identification signals, realistic electronic warfare and communications, and navigation for testing electronic warfare equipment.

The Air Force awarded a contract to Northrup in early 2013 to use CEESIM intesting the AN/ALR-69 radar system.   

The APG represents an increase in testing capability in relation to next generation receiver test requirements. Northrup Grumman said in an announcement that the APG can be retro-fitted into any existing CEESIM systems as an upgrade or can be included into new designs, and is designed to be modular and adaptable for range, laboratory or anechoic chamber functions.

The APG generates radio frequency waveforms through the use of direct digital synthesizer technology that allows advantages such as reduced calibration time, higher resolution and precision, wider bandwidth intrapulse modulation, higher modulation sample rates, and reduced cost and increased system reliability through lower RF part counts. The system also includes an updated user-interface designed to be more intuitive and to increase customization.
