Product Introduction

Functional Description:

This product is designed primarily for testing automotive millimeter-wave radar systems. The radar under test (DUT) is placed in an electromagnetic shielding chamber, maintaining a distance of approximately 1 meter from the simulator antenna. Using dedicated simulator control software, users can set target simulation parameters such as distance, speed, and radar cross-section (RCS) to calibrate and test radar performance.

Product Components:

The target simulator consists of two main modules: the millimeter-wave front-end module and the baseband module.
