Northrop Grumman has introduced advanced pulse generation (APG) technology, with direct digital synthesis, to test and validate the performance of electronic warfare equipment.
The APG, which successfully completed detailed performance testing, is claimed to be the next technology evolution for the company’s combat electromagnetic environment simulator (CEESIM) product.
Northrop Grumman Amherst Systems business unit site director Joe Downie said the company’s continued investment in the APG development demonstrates its ability to meet customers’ need for next generation advanced threat capabilities while ensuring the company’s products are sustainable and adaptable to evolving requirements.
"The advanced waveform generation, when coupled with our advanced angle-of-arrival modeling and controlled by our state of the art graphical user interface, immediately transforms the CEESIM system into the most powerful, most advanced electronic warfare simulator available," Downie said.
The high speed direct digital synthesizer (DDS) technology feature of the APG generates radio frequency (RF) waveforms to offer significant advantages to the user, including higher modulation sample rates, wider bandwidth intrapulse modulation, higher precision and resolution, and reduced calibration time.
The DDS capability also helps users to reduce RF part count, thus reducing cost and increased system reliability.
The CEESIM is an advanced technology simulator designed to generate complex dynamic electromagnetic environments to simulate true-to-war conditions.
Capable of providing angle-of-arrival radio frequency simulation techniques such as phase, amplitude and time difference of arrival, the system features an updated user interface that makes programming complex emitters more intuitive.
Designed with open architecture modularity and flexibility to be adaptable for use in laboratory, anechoic chamber and range applications, the APG can be included in new simulator designs or back-fit into any existing CEESIM simulators as an upgrade.
