Abstract
The present disclosure relates to an apparatus and method for processing interference signal of an automotive radar, and more particularly, to an apparatus and method for processing interference signal of an automotive radar to detect and cancel interference signal of the automotive radar.
Claims19
An apparatus for processing interference signal of an automotive radar, the apparatus comprising:
- a signal receiver including a main receiver for receiving an external signal in order to detect a target signal and a sub-receiver for detecting an interference signal with respect to the target signal;
- a first filter configured to detect a first received signal from the external signal received from the main receiver;
- a second filter configured to detect a second received signal from the interference signal received from the sub-receiver;
- and
- a processor configured to process the first and second received signals detected through the first and second filters,
- wherein the processor is configured to obtain a target signal from which the interference signal has been canceled by subtracting the second received signal from the first received signal.
An apparatus for processing interference signal of an automotive radar, the apparatus comprising:
- a signal receiver including first and second antennas, first and second antenna switches respectively connected to the first and second antennas, and a first processor configured to control the first and second antenna switches according to a result of determination based on predetermined conditions with respect to a state of an automotive radar, and configured to detect an external signal and an interference signal with respect to a target signal in order to detect the target signal from RF signals received from the first and second antennas;
- a first filter configured to detect a first received signal from the external signal;
- a second filter configured to detect a second received signal from the interference signal;
- and
- a second processor configured to process the first and second received signals,
- wherein the second processor is configured to obtain a target signal from which the interference signal has been canceled by subtracting the second received signal from the first received signal, and
- the signal receiving unit is connected only to the first antenna to detect the external signal and the interference signal from a signal received from the first antenna or connected to both the first and second antennas to detect the external signal and the interference signal from signals received from the first and second antennas by the first processor controlling the first and second antenna switches.
A non-transitory computer-readable storage medium storing a computer program, which comprises instructions for a processor to perform a method for processing interference signal of an automotive radar, the method comprising:
- receiving an external signal through a main receiver in order to detect a target signal and receiving an external signal through a sub-receiver in order to detect an interference signal with respect to the target signal in an apparatus for processing interference signal of an automotive radar in which the main receiver and the sub-receiver are connected to at least one antenna;
- obtaining a first received signal by applying a filter to the external signal received from the main receiver;
- obtaining a second received signal by correcting the interference signal received from the sub-receiver;
- and
- obtaining a target signal from which the interference signal has been canceled by subtracting the second received signal from the first received signal.
