摘要： A radar includes a transmitter antenna unit including a plurality of transmitter antennas based on a first horizontal interval and a first vertical interval, a receiver antenna unit including a plurality of receiver antennas arranged based on a second horizontal interval, a transceiver configured to transmit a transmission signal through the transmitter antenna unit and receive a reflection signal reflected from a target object through the receiver antenna unit and a processing unit configured to extract information about the target object by processing the received reflection signal. The second horizontal interval is smaller than the first horizontal interval.

摘要： A security apparatus forms a virtual security area. The security apparatus includes a radar sensor that transmits and receives a signal; and a reflector that reflects a signal output from a radar sensor of another security apparatus adjacent to the security apparatus. The security apparatus transmits a signal to a reflector of the another security apparatus adjacent to the security apparatus and receives a signal reflected by the reflector of the another security apparatus through the radar sensor to form a virtual security area between the security apparatus and the another security apparatus.

摘要： An object detection radar apparatus is installed in a vehicle and is configured to detect an object. The object detection radar apparatus includes a transceiver configured to transmit a radar signal to the 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 a predetermined event 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 when the predetermined event occurs.
