Radar Target Generation for Angular Resolution Testing in a Compact Test Range with Two Antennas

This work presents a ray-tracing simulation approach for an automotive compact radar test range. The goal is to generate two targets separated in azimuthal direction to test the angular resolution of a radar under test. The setup is programmed as a ray-tracer in Matlab, with the application of a wave function to the rays. The effects which occur due to the offset of the antennas from the focus point are analyzed. The system is realized with movable antennas to enable different angular distances.
