Radar sensor and method for controlling same to reduce the crosstalk of digital signals to the HF radar signal

摘要

The radar sensor has a transceiver device for generating a radar signal having a settable output power, a control unit and an interface unit. The transceiver device may be controlled via a digital interface via the interface unit and the control unit. One of the lines of the interface is connected to the control unit, the control unit being designed in such a way that when a predetermined level is present on this line, the output power of the transceiver device is lowered.

1. A radar sensor comprising:
a transceiver device to generate a radar signal, output power of the transceiver device being settable; a control unit; and an interface unit including a digital interface to control the transceiver device, wherein:
the digital interface is a serial interface that includes a plurality of lines;the plurality of lines include a line for a selection signal, a line for a clock signal, and a line for at least one data signal;the line for the selection signal is connected to the control unit; andthe control unit is configured to lower the output power of the transceiver device in response to the line for the selection signal being set at a predetermined level.
