EEsof gains radar and EW modelling and verifications capabilities

May 20, 2014 // By Graham Prophet
Agilent Technologies' EEsof EDA W1905 radar model library has been enhanced to simulate moving 3-D radar scenarios as well as phased-array adaptive beamforming.

The new modelling capability saves design verification cost and accelerates deployment for radar system engineers. It also reduces dependence on expensive field testing and dedicated hardware emulators by realistically rendering radar and electronic warfare environments economically throughout the R&D process, using commercial design software and test equipment.

The W1905 radar model library is available as a simulation option to SystemVue, Agilent’s platform for electronic system-level design. The enhancements add inertial modelling “layers” above the baseband radar signal processing references. They account for the 3-D positions, velocities, rotations and beamforming directions of each transmitter, receiver and target, allowing modellers to create and script meaningful airborne, shipborne and multi-static scenarios or environments. Together with models for dynamically steerable antenna arrays and adaptive digital beamforming, the effectiveness of radar architectures and counter-measures can be quickly assessed, while also accounting for clutter, jammers, interference and RF analog limitations.

The choice of SystemVue as an integrated “system-level cockpit” connects radar architects to other critical R&D domains, including:

- baseband algorithm design interfaces in floating-point math, C++, or HDL;

- accurate RF models from Agilent’s Advanced Design System (ADS) and EMPro 3-D EDA software;

- industry-leading wideband test and measurement equipment, such as Agilent’s M8190A arbitrary waveform generator and M9703A 8-channel digitizer, to generate and capture simulated waveforms for hardware validation, and;

- optional links to external applications, such as the STK software from Analytical Graphics, Inc.

By connecting the new realistic scenarios with other technology references, SystemVue allows radar system architects to affordably, validate radar and electronic warfare architectures using commercial tools, while also using their own secure IP.
