Patent number: 11635489Abstract: A method for the use in a radar system is described herein. In accordance with one embodiment, the method includes providing a local oscillator signal to an RF output channel of a radar system. The RF output channel is configured to generate, in an enabled state, an RF output signal based on the local oscillator signal. The method further includes determining a first measurement signal based on the local oscillator signal and a first representation of the RF output signal, while the RF output channel is disabled, and thus the first measurement signal represents crosstalk. Further, the method includes determining a second measurement signal based on the local oscillator signal and a second representation of the RF output signal while the RF output channel is enabled. A phase value associated with the RF output channel is determined based on the first measurement signal and the second measurement signal.Type: GrantFiled: June 23, 2020Date of Patent: April 25, 2023Assignee: Infineon Technologies AGInventors: Vincenzo Fiore, Werner Arriola, Rene Kobler, Oliver Lang, Alexander Melzer
