ASES

The Advanced Signal Environment Simulator (ASES) is designed to replicate complex, dynamic, and realistic electromagnetic environments. It can generate radar, communication, and navigation signals in real time, including radiation source signals, background signals, and clutter pulse streams. This system is ideal for building complex electromagnetic environments for field testing and performing hardware-in-the-loop (HIL) simulations for electronic warfare (EW) systems. By simulating high-density radar signals and multi-type modulation patterns, ASES provides a reliable platform for performance evaluation, algorithm verification, and system-level testing in defense and aerospace applications.
