There is provided a radar apparatus wherein a local signal having a coherent sine wave is modulated to generate a composite signal of two signals modulated by different modulation functions. The composite signal is transmitted as a transmission signal, and a reception signal associated with the transmitted signal is separated into two signal components modulated by the different modulation functions. A difference between the two signal components is found, thereby removing a reflection signal from a static clutter and extracting a signal component which has been frequency-deviated by a moving target. Thus, the moving target is displayed. The transmission frequency can be quickly changed without losing the function of detecting the moving target.
