Application of two movable antennas in a compact radar test range for angular measurements

Abstract. This work presents the application of two movable antennas in a compact radar test range for testing the angular resolution of radar systems in an automotive environment. The goal is to simulate two targets in the azimuth direction, which are measured by a radar placed in the quiet zone. At first, a mathematical approach to the problem is presented. Afterwards, a ray tracer in MATLAB is used for the setup simulation, and measurements are carried out to validate the calculation and simulation results. The effects occurring in the simulation and measurements are analyzed, and strategies to mitigate them are presented. Overall, the results look promising, and the system is suitable for testing the angular resolution of radar systems.
