SRES

The Satellite-Borne Radar Echo Simulator (SRES) is an advanced testing solution designed to generate multi-channel, distributed radar echo signals for satellite-based radar systems. It supports comprehensive functional and performance verification throughout research, production, and ground integration testing phases. The system provides precise simulation of satellite constellations, orbital dynamics, antenna positioning, and ionospheric effects, enabling realistic radar operation scenarios.

SRES can emulate both static and dynamic scenes, including high-resolution SAR imaging and GMTI target detection, ensuring accurate performance evaluation under diverse conditions. With real-time signal generation, multi-mode radar support (SAR, GMTI, AMTI), and advanced error injection capabilities, this system is essential for validating next-generation satellite radar systems prior to deployment.
