The MARS software provides a real-time simulation of modern airborne radar systems. It models key radar modes, antenna patterns, terrain, weather, and targets. MARS can be customized for specific radars and integrated into flight simulators. It implements physical models to accurately simulate radar performance and interactions with the external environment.

- 1. The MARS, Multimode Airborne Radar Simulator, is a software tool which provides a real-time computer simulation of the principal A/G and A/A radar modes of modern airborne pulse-doppler radars. Designed to be easily integrated into different flight simulators, the tool is currently in use in the Eurofighter Typhoon simulators for the European Typhoon consortium ASTA. MARS - MULTIMODE AIRBORNE RADAR SIMULATOR MAIN FEATURES • Simulation of the principal Air-to-Surface non-coherent modes: Real Beam Ground Mapping (RBGM), Sea Surface Search (SSS), Air to Surface Ranging (ASR) • Simulation of high resolution radar mapping modes (SAR modes, DBS modes), reproducing the base-band IQ signals of the received echoes and the FFT processing • Synthetic detection and tracking capabilities: HPRF, MPRF, LPRF detection modes, Ground Moving Target Indicator (GMTI), Range While Search (RWS), Velocity Search (VS), Track While Scan (TWS), Single Target Tracking (STT) • Parametric models for the antenna gain patterns • Simulation of sum and difference channels, monopulse measurements • Customisable simulation of: STC, Pulse compression, Log amplifier, CFAR processing • ECM simulation: continuous wave (CW) and deception jammers • Swerling models for target radar cross sections • Different Weibull statistics for terrain reflectivity. • Sea reflectivity modelled according to Beafourt scale • Rayleigh statistics for thermal noise • Multipath effects: far shore brightening, building edge brightening • Complex weather simulation: different precipitation types and intensities, arbitrary shaped clouds arbitrarily positioned in the scenario, turbulence and vectorial 3D wind field • Real-time terrain database viewer facility GENERAL DESCRIPTION MARS implements physical/mathematical models of the radar devices and of the external environment. Its structure allows customisations for the simulation of specific radar equipment. Many parameters from the data package of a real radar apparatus can be inserted directly into the tool configuration files, maximizing the fidelity of the radar simulation. MARS is entirely a SW COTS product and requires standard commercial hardware only. It is written in ANSI C/C++ and it is platform independent. It has been released for SGI, Microsoft Windows and Linux distributions. The tool offers the user a shared memory that can be filled at runtime by the simulation host when integrated inside a simulation system (DRLMS) or by the MARS GUI when

Remote communication for distributed simulations has been foreseen and implemented (UDP, DIS, HLA). The processing of the MARS tool has been paralysed in order to take advantages of the availability of multi-processor platforms. The MARS DBGS is the offline software tool developed to build the radar scenario database for the MARS real-time system. Designed to import and manipulate several input formats, such as OpenFlight files, DTED files, ESRI shapefiles etc., and to process all of the data together to automate the MARS real-time DB generation workflow, it provides numerous options to tailor the DB generation process.
