A radar is provided to obtain an accurate speed of an object to be monitored by removing a clutter from a reflected signal and suppressing and power leakage of the radar. A radar includes a transmitter-side frequency processor(100), a transmission antenna(200), a reception antenna(300), a receiver-side frequency processor(400), a signal processor(500), and a band reject filter(460). The transmitter-side frequency processor generates and outputs a high frequency monitoring signal. The transmission antenna transmits the monitoring signal. The reception antenna receives a reflected signal, which is Doppler-shifted by an object, from the monitoring signal. The receiver-side frequency processor receives the reflected signal and down-shifts the reflected signal, such that a Doppler frequency is obtained. The signal processor processes the Doppler frequency and obtains an object speed. The band reject filter is arranged in the frequency processor and removes a clutter and a transmission leakage power from the reflected signal.
