1. A radar device comprising:
a first module for generating a first transmission signal using a first local oscillation signal, transmitting the first transmission signal, receiving a reflection signal of the first transmission signal, and generating a first reception signal from the received reflection signal using the first local oscillation signal;
a second module for receiving the reflection signal of the first transmission signal, and generating a second reception signal from the received reflection signal using a second local oscillation signal that is synchronized with the first local oscillation signal; and
processing circuitry performing a process of:
detecting a target using the first reception signal and calculating an angle of the target using, for the target, a signal obtained by coherent integration based on the first reception signal and the second reception signal.
