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.

Description

Background technique [0001] Radars is a useful device that can detect and track objects. Relative to other types of sensors (such as cameras), radar can provide improved performance in situations where different environmental conditions, such as low illumination and fog, or overlapping objects. Therefore, radar provides many advantages for autonomous driving applications or driver assist applications. [0002] When designing and developing radar, engineers can perform field tests (for example, real-time testing) to assess radar performance. However, the field test will be expensive and time-intensive. In addition, these tests are usually happening after design and implementation. Therefore, there may be a lot of rework and additional costs when solving the problems disclosed on-site testing. Inventive content [0003] Describe technology and apparatus for realizing high-fidelity radar simulators. The radar simulator performs the operation associated with the hardware and / or sof...
