The invention discloses a road condition detection method based on radar communication integration, and the method comprises the steps that 1, a main station radar transmits radar communication integration signal pairs s1 (k) and s2 (k) at the moment k, and obtains the detection information I (k) of vehicles and obstacles in a road segment according to echo signals; 2, at the k + 1 moment, the main station radar transmits radar communication integrated signal pairs s1 (k + 1) and s2 (k + 1), and vehicle and obstacle detection information I (k + 1) in the road section is obtained according to echo signals; the detection information I (k) at the moment k is modulated into s1 (k + 1) and s2 (k + 1) by changing the width of each pulse in s2 (k + 1); 3, the vehicles in the road section receivethe radar communication integrated signal pairs s1 (k + 1) and s2 (k + 1), and the detection information I (k) at the last moment is obtained from the radar communication integrated signal pairs; according to the method, a radar signal used for detecting a target and a communication signal used for transmitting detection information are realized by using a group of equal-period pulse signal pairs,so that electromagnetic resources are saved on the basis of realizing a road condition detection function.
