Bistatic Analyst (Also see the Bistatic Analyst FAQ.)

Polatin Corporation’s Bistatic Analyst tool is a well-validated, physics-based simulator for modeling the monostatic and bistatic radar return from terrain located almost anywhere in the world over a broad range of environmental conditions. The modeling approach used in this software is based on a combination of discrete component Monte-Carlo simulations and quasi-statistical methodology. The basic concepts and techniques are the cumulative result of more than 15 years of research in the course of which extremely fast and CPU efficient simulation algorithms have been developed.

The Bistatic Analyst software package includes integration of these models and techniques into an easy-to-use, GUI-driven simulator code which incorporates DTED and land-cover/land-use databases for geo-referencing. The integrated software product has a flexible and convenient map-driven interface and can be run on either single standalone PC nodes or large network-distributed architectures. It is anticipated that this product should provide the user communities with a state-of-the-art capability for simulating the monostatic and bistatic radar reflectivity of terrain and should serve as a useful adjunct to future radar programs.

High Fidelity Terrain Simulator capabilities include:

• 1 GHz to 20 GHz polarimetric operation

• Variable Tx/Rx standoff configuration

• Wide variety of accurate, physics-based terrain scattering models for homogeneous and mixed terrain

• Grazing angle, out-of-plane, frequency and monostatic scans

• Global, geo-specific terrain inputs, including standoff/shadowing

• Sigma0 or complex scattering matrix output

• Variable resolution (1 m to 10 m)

• Generates histograms, line plots, and probability density functions

• GUI-driven software

• Distributed computing capability

• Simulation databasing

Some key features of Bistatic Analyst include:

• Flexible parameter input structure

• Map underlay and drill-down

• Simulation database (store and analyze data)

• Distributed simulation capability (network based)

• Input visualization

• Data plots and histograms

• Output data to text file

Available Terrain Categories:

Agricultural land	Open ground
Shrub and wasteland	Grasslands
Broken woodlands and savannas	Wetlands, marshlands, and swamps
Coastland	Forests; deciduous, conifer and mixed
Bodies of water	Desert
Shrublands	Pavement
Snow Cover	User-defined mixed terrain

Global Terrain Definition Capabilities:

• Digital elevation model inputs:
  • Synthetic DEM (levels 0 through 5)
  • DTED (levels 0 through 2)
• USGS LULC inputs.
• VMap input scheme for drill-down orientation.
