Abstract: A method includes techniques for identifying the phase step of one transmitter while conducting phase difference measurements between two transmitters in a multi-transmitter radar device. The method includes setting a first phase of a first transmitter in the multi-transmitter device to a fixed phase value and setting a second phase of a second transmitter in the multi-transmitter device to an initial phase value, varying the second phase of the second transmitter from the initial phase value to a final phase value and performing a sample measurement at each variation to obtain a plurality of intermediate frequency (IF) samples; and transforming the plurality of IF samples into complex samples. The method then includes determining one or more phase steps of the second transmitter based on the complex samples.
