Radar detector having function of hands-free device

Abstract

The present invention relates to a radar detector having the function of a hands-free device, so that it is possible to talk over a mobile phone in a hands-free manner by connecting the mobile phone to the radar detector. The radar detector comprises a horn antenna 100; a signal-processing unit 200 for detecting a signal received by the horn antenna 100; a laser module 300 for receiving a laser signal; a central processing unit 400 for controlling the signal-processing unit 200 by generating a pulse to measure and calculate the period and width of the signal detected by the signal-processing unit 200, to analyze and output the bandwidth and information of the signal, and to find the type and information of the signal over time; a pulse delay unit 500 for delaying or sustaining the pulse received from the central processing unit 400; a sweep voltage generator unit 600 for driving the signal-processing unit 200 by generating a voltage from the pulse delay unit 500; a warning unit 700 for audibly or visually warning the detected signal; an audio amplifier controller 800 connected to the central processing unit 400 and the warning unit 700 to amplify an audio signal; and a mobile phone connecting unit 900 installed to connect the audio amplifier controller 800 with a mobile phone 10 and including a microphone 910, a switch 920 for reception of a signal from the mobile phone, and a connection portion 930 for connection to the mobile phone. According to the present invention, a user can talk over a mobile phone using an additional function of the radar detector, without a need for mounting an additional hands-free device for conversation by the phone in a vehicle with the radar detector installed therein, thereby improving user's convenience.
