Radar apparatus and method for detecting object based on occurrence of event

An object detection radar apparatus that is installed in a vehicle and configured to detect an object, comprising:

• a transceiver configured to transmit a radar signal to an outside of the vehicle and receive a radar signal reflected from the object;
• a driving environment detector configured to detect a driving environment of the vehicle based on an operation status of the vehicle;
• an object detector configured to detect the object based on the received radar signal;
• and
• a controller configured to:
• determine whether or not curve driving of the vehicle occurs based on the driving environment of the vehicle or a result of the detection of the object, and
• control signal characteristics of the transmitted radar signal or the received radar signal in response to determining that the curve driving of the vehicle occurs,
• wherein in response to determining that the curve driving of the vehicle occurs, the controller controls a number of transmitter antennas connected to the transceiver, and
• the object detector is configured to decrease the number of transmitter antennas in response to determining that the curve driving of the vehicle occurs.
