Examples of E-field Capabilities

These include, but are not limited to:


Development, implementation, assessment and/or recommendation of computer simulation models allowing prediction of:


                     Link performance and system coverage for fading, interference limited channels over arbitrary terrain types and surface covers, with or without ducting and other atmospheric effects.

                     Interference effects by multiple co-channel emitters in fading environments.

                     Channel capacity of systems constrained by transmitter and receiver intermodulation products resulting from the close proximity of system elements.

                     Propagation & performance models and terrain database requirements of Automated Spectrum Management and Electronic Warfare Analysis Systems for both analog and digital data.

                     Conventional, agile or wideband radar and communications intercept/DF/countermeasures system performance in realistic tactical or strategic environments

                     Satellite and airborne synthetic aperture radar performance.

                     Relative performance of systems having different operating parameters such as frequency, location and antenna height / directivity.


Technical literature searches and subsequent system performance analyses in terms of parameters such as:


                     Delay-spread, spatial correlation and signal fading distributions.

                     Rainfall and refractivity data for any part of the world.

                     Terrain radio-frequency reflectivity measurements as a function of surface type.


Design, implementation and evaluation of field trial measurement programs to validate system performance models for:


                     Transmitter/Sensor coverage

                     Interference probabilities

                     Intercept range

                     Detection probabilities

                     Direction-Finding accuracy

                     Countermeasures performance


Delivery of customized training courses in:
