Abstract
A signal generation circuit, a radar apparatus, and a signal control method are provided. The signal generation circuit includes a digital-to-analog converter (DAC) and a mixer. The DAC is configured to convert an input digital signal into two signals in a first mode. A coding content of the input digital signal includes multiple bits. The mixer is coupled to the DAC to respectively input the two signals converted from the input digital signal to two input ports of the mixer in the first mode, to generate an output signal. An output power of the output signal corresponding to the input digital signal having a first coding content is different from an output power of the output signal corresponding to the input digital signal having a second coding content. An intensity of the output signal is related to a voltage difference between the two signals converted from the input digital signal.
