Scene Simulation Software
Our scene simulation package represents a state-of-the-art tool for the creation of both hybrid and synthetic aperture radar (SAR) full-scene imagery. Hybrid image generation is accomplished through the insertion of synthetic targets into measured imagery. In contrast, full synthetic scene simulation uses a 3D world model consisting of 3D terrain digital elevation maps (DEMs), geo-registered land-user/land-cover maps, 3D parametric tree models, and statistical scattering representations to predict the background scene content, including shadowing, layover, and slope effects.
The 3D terrain inputs typically utilize a wide range of geographic information systems (GIS) to provide realistic SAR simulations for a variety of mission and system analysis scenarios. We have implemented an advanced X-band clutter statistics extraction technique to accurately model and process new clutter types. A complementary clutter generation process is implemented in this product. This new data synthesis approach allows for extensibility in SAR system parameters including resolution, frequency, and polarization while limiting the representative data growth. Additional efforts are also focused on the online updating and refinement of the 3D world model in terms of geo-registered land-use/land-cover and tree parameter refinement.
Imagery produced by the simulation can be used for evaluating automatic target recognition (ATR) performance through a wide range of extended operating conditions or in training simulators. Unlike measured data collections, synthetic simulations are not limited in terms of scene center or acquisition geometry. Since the predictions are based on a 3D world representation, the user is free to specify the scene center location and the sensor acquisition geometry. Another valuable product of the simulation is the automatic generation of the associated ground truth, which is typically lacking or of questionable fidelity and accuracy in many measured collections.
Apatch™ Antennna Simulation Software
The Apatch™ software is an advanced modeling tool for the radiation and coupling analysis of installed antennas on aircraft, ships, and in other complex 3D environments. Based on the same proven shooting-and-bouncing ray (SBR) technology used in the Xpatch® tookit for efficient and high-fidelity electromagnetic modeling, these codes help engineers manage the interplay between the effects of antenna placement, vehicle geometry, and use of electromagnetic (EM) transparent protective materials.

AntFarm™ Antenna Simulation Toolkit
The AntFarm™ toolkit integrates the proven modeling technologies of the Apatch software with mature 3D visualization capabilities into a single package. The AntFarm toolkit analyzes the radiation and electromagnetic interference (EMI) effects of single or multiple heterogeneous RF systems. Analysis can be restricted to isolated systems or conducted in situ on the multisystem platform. See photo

Urbana™ 3-D Wireless Toolkit
The Urbana™ toolkit is a suite of tools for predicting and visualizing coverage and multipath delay-spread signaling by terrestrial and satellite base stations in complex indoor and outdoor environments. Through its 3D visualization of buildings and antenna radiation characteristics, coupled with a corresponding modeling capability, effects of adaptive antenna beam-forming, polarization, and other novel/emerging approaches to base station and mobile unit design also can be studied.
