Abstract
A radar device comprises at least one transmitter unit for transmitting a radar signal, at least one receiver unit for receiving a reflected radar signal, and a phase shift unit for producing a phase shift in the frequency modulated radar signal in response to a phase shift signal. The receiver unit comprises at least one filter unit for filtering the received signal and is arranged for resetting the filter unit in response to said phase shift signal, so as to avoid saturation of the filter unit due to the phase shift.
Claims20
A radar device, comprising:
- at least one transmitter unit for transmitting a radar signal,
- at least one receiver unit for receiving a reflected radar signal, the receiver unit comprising at least one filter unit for filtering the received signal, and
- a phase shift unit for producing a phase shift in the transmitted radar signal in response to a phase shift signal,
- the receiver unit being arranged for providing a reset of the at least one filter unit in response to said phase shift signal so as to suppress undesired filter states.
A method of operating a radar device comprising:
- at least one transmitter unit for transmitting a radar signal,
- at least one receiver unit for receiving a reflected radar signal, the receiver unit comprising at least one filter unit for filtering the received signal, and
- a phase shift unit for producing a phase shift in the transmitted radar signal in response to a phase shift signal,
- the method comprising providing a reset of the at least one filter unit in response to said phase shift signal so as to suppress undesired filter states.
