This document describes techniques and systems for enabling more-accurate single-point radar cross section (RCS) approaches for radar simulations without introducing orders of complexity. For automotive radar applications, considering variations in RCS radial patterns, with both angle and range, and because of analytically calculated multi-path effects and near-field RCS effects improves simulation accuracy by incorporating multi-path phenomenon that is present due to ground reflections. The described techniques are performed without using full scale ray-tracing or other computationally demanding techniques.

Single-point radar cross section approaches for radar simulation

This document describes techniques and systems for accurate and efficient electromagnetic response for a sensor simulator. Target information and sensor parameters for an electromagnetic sensor are simulated in an environment that includes a ground plane. Electromagnetic rays that may be detected by the sensor or an image of the sensor are launched from the simulated sensor toward the target and an image of the target about the ground plane to determine a complex electromagnetic response of the target. A ray-tracing algorithm is applied to trace the forward wave propagation of electromagnetic rays in the environment that considers rays bouncing between the target and the image of the target. An electromagnetic response can be modeled based on the congregation of the electromagnetic response of all backward paths of all bounces of all rays. In this manner, an efficient and accurate electromagnetic response model may be approximated.
