Abstract: A method for the use in a radar system is described herein. In accordance with one implementation, the method includes providing a local oscillator signal to a transmit channel of a radar chip. The transmit channel generates an RF output signal based on the local oscillator signal. An internal RF test signal is generated by applying the local oscillator signal to the transmit channel. First and second phase values are determined for a first and a second value of an influence parameter of the radar chip based on internal measurements of the first and second phase values. Third and fourth phase values are determined for the first and second values of the influence parameter, respectively, based on the RF output signal. A calibration parameter is calculated based on the first, second, third, and fourth phase values and is used to estimate a phase of the RF output signal.
