Abstract

The invention discloses a microwave radar type automobile anti-collision early warning system. The microwave radar type automobile anti-collision early warning system mainly comprises a signal collecting system, a data processing system and a display terminal. The signal collecting system comprises a radar sensor, a triangular wave modulation module and an echo analog signal preprocessing module. The signal collecting system is installed at the front end of an automobile and is connected with a digital signal processing module through a line, wherein the digital signal processing module is also installed at the front end of the automobile. The display terminal comprises an LCD display module and a voice alarm module which are installed in the automobile and are connected through a wireless transmission module. The microwave radar type automobile anti-collision early warning system has the advantages of being economical, practical, easy to achieve and the like, and can quickly and accurately detect front vehicle information and find dangerous targets and give an alarm in real time to guarantee safe running.

Description
