To discuss a system based on Cortex-M3 kernel chip with TFT for displaying distance between two moved cars,the paper expounds the system work principle,the hardware structure and software process and the mil imeter wave FMCW FM continuous wave radar was used to transceiver data.Then data was treated accurately and effectively through the DSP.The system can detect the distance from front target cars and the distance displaying is real-time in the TFT.Also,it display three reference pictures in the TFT for tel ing driver the car is getting closer or further to the front obstacle.When the distance exceed secure value,the system can help drivers to know road condition and deal with situation timely.So it can reduce the incidence of traffic accidents.
