Abstract
This paper introduces a radar sensing early warning system designed and implemented based on CYCLONE IV series FPGAs, which generates PWM signals to control the rotation of servo through parallel high-efficiency FPGAs, and at the same time generates trigger signals to drive the ultrasonic radar to detect obstacles, and if the set distance is reached, the buzzer will sound an alarm, and display the current servo angle and distance to the obstacle through the LCD, so as to achieve the effect of radar early warning—radar warning effect.
