6 Summary

The receiver ADC saturation can significantly impact radar functionality and leads to the loss of crucial information from the reflected signal of the target object. Additionally, a higher noise figure degrades the overall performance of the radar by reducing the SNR, which consequently affects both the range and angle resolution. The recommendations provided for selecting transmitter power backoff and receiver gain settings for the xWRL6432AOP radar device are intended to create the best possible performance. These guidelines address how improper settings can result in higher EINF due to noise in the TX-RX coupled signal and the risk of receiver ADC saturation from low-frequency signals at the RX output. Recommendations are provided to achieve the most favorable settings on xWRL6432AOP radar devices based on the end application, thus enhancing radar performance by managing the impact of these issues.
