Dynamic echo signal emulation for automobile radar sensor configurations

Abstract:

A system for testing automobile radar sensor configurations includes multiple probe arrays, multiple enclosures, a channel emulator and a test controller. The enclosures each enclose one of the probe arrays together with a corresponding different automobile radar sensor. Each probe array is configured to receive radar signals from the corresponding automobile radar sensor and emulate echo signals back to the corresponding automobile radar sensor. The channel emulator is configured to supply the echo signals to each of the probe arrays. The test controller includes a memory that stores instructions and a processor that executes the instructions. The test controller controls the channel emulator and is configured to perform performance testing on an automobile radar sensor configuration that includes the automobile radar sensors and an automobile driving controller that reacts to the echo signals received by each of the automobile radar sensors.
