1. Radar determination circuitry configured to:
obtain a first received radar signal representing a first transmitted radar signal reflected at a scene;
obtain a second received radar signal representing a second transmitted radar signal reflected at the scene, wherein
the first transmitted radar signal and the second transmitted radar signal have a common chirp repetition frequency and a same frame length, enabling simultaneous processing of data corresponding to the first and second transmitted radar signals, and wherein
the first transmitted radar signal is based on a first carrier frequency and the second transmitted radar signal is based on a second carrier frequency different from the first carrier frequency;
simultaneously process the first received radar signal and the second received radar signal;
determine a first measured parameter based on the first received radar signal, the first measured parameter being subject to a measurement ambiguity;
determine a second measured parameter based on the second received radar signal, the second measured parameter being subject to a measurement ambiguity; and
compare the first measured parameter and the second measured parameter to determine an unambiguous parameter.
