The approaching target is detected using a beat frequency which corresponds to the frequency difference of a received CW signal and a transmitted CW signal. The modulation controller produces the speed and the distance of the approaching target. A modulation bandwidth is set according to calculated speed and distance. The CW-LFM signal generator generates a CW-LFM signal which a preset modulation bandwidth is applied to. A generated CW-LFM signal is transmitted through the RF transmitter.
