Abstract
A radar system including a narrowband radar receiver configured to receive pulsed radar return signals and a wideband receiver configured for receiving wideband signals. A noise data processor is configured to identify impulse noises by analyzing wideband signals received by the wideband receiver and a radar processor is configured to cancel the identified impulse noises from pulse signals received by the radar receiver. The wideband impulse noises utilized to cancel noise from the pulse signals corresponds to the same time period sweep of detection as that of the pulse signals.
Claims14
A radar system, comprising:
- a narrowband radar receiver configured to receive pulsed radar return signals.
- a wideband receiver configured for receiving wideband signals;
- a noise data processor configured to identify impulse noises by analyzing wideband signals received by the wideband receiver;
- and
- a radar processor configured to cancel the identified impulse noises from pulse signals received by the radar receiver.
A method for cancelling noise in a radar system, the method comprising:
- detecting radar return pulses with a receiver configured for receiving the return pulses;
- detecting wideband signals transmitted during the same time sweep as detected return pulses;
- identifying regions of impulse noise within the wideband signals that would corrupt the return pulses;
- and
- cancelling the identified impulse noise from the return pulses.
