RADAR DEVICE, METHOD OF DETECTING FAILURE OF RADAR DEVICE, AND METHOD OF OPERATING RADAR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18515301 titled 'RADAR DEVICE, METHOD OF DETECTING FAILURE OF RADAR DEVICE, AND METHOD OF OPERATING RADAR DEVICE
Simplified Explanation
The radar device described in the patent application utilizes a transmission module to generate a transmission chirp signal, which is then received by reception modules. These reception modules receive both a reflected wave and a direct wave of the transmission chirp signal, and perform mixing on the received signal using a reception chirp signal. A signal processing unit within the radar device detects targets based on the beat signal resulting from the mixing performed by the reception modules. Additionally, the signal processing unit can detect the level of the beat signal generated from the received direct wave, and determine a failure of the radar device by comparing this level with a threshold set based on a beat signal level measurement under specific environmental conditions. The transmitted chirp signal is also used as the reception chirp signal.

Original Abstract Submitted
A radar device includes a transmission module that generates a transmission chirp signal, and reception modules that each receive a reflected wave and a direct wave of the transmission chirp signal, and perform mixing on a received signal, using a reception chirp signal. The radar device includes a signal processing unit that detects a target on the basis of a beat signal resulting from the mixing performed by the reception modules. The signal processing unit detects a level of the beat signal generated from the received direct wave. The signal processing unit determines a failure of the radar device by comparing the detected level with a threshold set on the basis of a beat signal level measurement under an environment that eliminates the reflected wave in advance. The transmitted chirp signal distributed from the transmission module is used as the reception chirp signal.
