US 2022/0188483 A1 · High-Fidelity Radar Simulator

Abstract

Techniques and apparatuses are described that implement a high-fidelity radar simulator that performs operations associated with a radar system's hardware and/or software. The radar simulator can account for non-ideal characteristics within the radar system or environment and have an ability to process data from a variety of electromagnetic (EM) simulators. By using the radar simulator, an EM simulator can operate without specific information regarding the radar system's antenna response or signal generation. In this manner, the EM simulator can be decoupled from the radar system's design and operational configuration. Furthermore, the radar simulator can use the same environmental response data generated by the EM simulator to estimate performances of multiple radar systems. Use of the high-fidelity radar simulator enables problems to be efficiently discovered during design, integration, and testing phases of the radar system prior to performing a live test.
