PURPOSE: A wide band radar detector with which a weather radio is combined is provided to prevent an accident and guide a stable driving by precisely judging a traffic situation while a driver drives a car and coping with a change of a weather. CONSTITUTION: A horn antenna(110) receives a signal. A signal processor(120) detects the signal received by the horn antenna(110). A laser module(130) receives a laser signal. A central processing unit(140) controls operations of the signal processor(120) and the laser module(130). An eyesight display device(150) visually displays the signal detected by the signal processor(120). A sound display device(160) outputs the detected signal to a speaker(162). A weather antenna(210) receives a weather broadcasting. A PLL controller(220) provides PLL(phase locked loop) data. A radio signal detector(230) is connected to the PLL controller(220) detects the received weather broadcasting according to the PLL data.
