RADSIM Radar Simulation 3.0

Overview

SAIC's RADSIM is a high fidelity radar simulation capability for flight simulators or mission planning systems. This software provides the fidelity and flexibility of a phototexture-based Digital Radar Landmass Simulation (DRLMS) system. It uses SAIC-developed core radar simulation technology and can produce geo-specific or generic, real time Synthetic Aperture Radar (SAR), Doppler Beam Sharpening (DBS), and real beam imagery.

Applications

RADSIM offers clear, high fidelity imagery that closely mimics how radar images will appear to the pilot in the cockpit. RADSIM is tailorable to either real-time flight simulators or mission planning systems. The mission planning version can be integrated into both mission planning and mission rehearsal systems. When integrated into the SAIC//MPS, RADSIM provides a complete package for the warfighter.

RADSIM uses a digital database created from overhead imagery; Defense Mapping Agency's Digital Terrain Elevation Data (DTED) and Digital Feature Analysis Data (DFAD), and other sources using SAIC's PHOTOMAP database generation tool. A library of sample databases is included with RADSIM. Specific radar effects, characteristics and capabilities of RADSIM provided by SAIC's core radar simulation technology include Doppler Beam Sharpening. For an example of the realism provided to aid flight simulator training, see this radar simulation closeup of a runway: See photo

• Accurate real beam, DBS, and SAR imagery from a single database.
• Portrayal of both cultural and terrain features.
• Accurate display of relocatable and moving targets with moving target indications.
• Simulation of either predefined areas of interest ("patches") or wide area coverage.
• Leading edge enhancement and far shore brightening.
• Cultural feature shadowing and terrain masking.
• Background texture and noise.
• Antenna pattern, side lobe, and tilt effects.
• Range attenuation and earth curvature.
• Receiver gain, Sensitivity Time Control (STC), and Fast Time Constant (FTC).
• Thunderstorm and Chaff effects.

Features

Interfaced to a host simulation, RADSIM provides accurate radar representations in the cockpit on either actual aircraft equipment or simulated displays. When installed on a user supplied computer, RADSIM provides a standalone, generic radar simulation capability that is suitable for classroom training and mission planning applications. The software automatically generates Reference Fix Point cards as a visual aid to assist with radar scope interpretation. See sample card

RADSIM operates with UNIX operating systems, or dual Pentium II processors running LINUX OS. It is compatible with workstation, PC or UNIX-based systems, and can be configured for a single user or network.

In addition to the RADSIM product, SAIC offers a number of additional services intended to customize and increase the program's utility and applicability. These services may be obtained by a separately negotiated support contract with SAIC. The following are representative support services available from SAIC:

• Custom Modifications - SAIC will modify RADSIM to provide for the realistic simulation of specific radar types. Specific map sizes, display resolution, unique radar effects and modes, and aircraft specific controls are examples of the types of tailoring efforts that SAIC can provide. RADSIM can be tailored for specific aircraft. See sample imagery for B-1, B-2, F-111C, and F-16.
• Training System Interface and Integration - RADSIM provides for a standalone radar simulation capability. For implementation with a specific training device (e.g., WST, CPT, etc.), SAIC will develop an appropriate system interface for RADSIM, either in its basic product form or as modified per customer unique requirements. In addition, SAIC offers a highly skilled staff of real time, simulation software engineers available to assist with systems integration.
• Computational Platform Rehost - RADSIM is hosted today on a PC and Silicon Graphics based systems. SAIC's design for RADSIM permits the product to be rehosted on other computational platforms that may be required by the customer. SAIC will assess the performance requirements associated with the customer's desired computational platform, define a hardware configuration necessary to support the operational requirements, and rehost RADSIM to this new configuration.

Benefits

Uses for the radar prediction capability include: Radar Terrain Masking Displays, Situation Analysis, Mission Planning, Mission Rehearsal, Radar Display Prediction and Aircraft Threat Susceptibility.
