Digilogic Systems offers an advanced Radar Target Echo Simulator (RTES) and Synthetic Aperture Radar Environment Simulator (SARES) that together provide realistic, high-fidelity radar testing in a lab environment. The DRFM-based RTES simulates radar targets, echoes, clutter and jamming effects with precise control over Range, Doppler and RCS, while SARES uses GPU-accelerated ray-tracing to generate accurate SAR signatures of 3D objects in real time. This combined solution allows radar designers to evaluate seekers, tracking radars and SAR systems under true field-like conditions with user-friendly scenario generation.
