Abstract
The present disclosure provides a radar apparatus including: an antenna including a first transmitting antenna, a second transmitting antenna, and a receiving antenna; a transmitter including a first modulator for generating a first transmission signal having an inverted phase of a source signal and transmitting the first transmission signal through the first transmitting antenna, and a second modulator for generating a second transmission signal having a shifted phase of the source signal and transmitting the second transmission signal through the second transmitting antenna; a receiver for receiving a reflection signal of the first transmission signal and the second transmission signal reflected from the object through the receiving antenna; and a controller for obtaining information for the object based on the reflection signal. According to the present disclosure, it is possible to efficiently detect the object using the antenna having a simple structure.
