The invention discloses an intelligent traffic detector based on high-resolution radar. The intelligent traffic detector based on the high-resolution radar comprises a high-resolution-radar detectionfront end, a real-time imaging back end and a communication transmission module, wherein the high-resolution-radar detection front end comprises an emission chain, a receiving chain and a frequency synthesis unit, a DDS unit is connected to the signal input end of the emission chain, and the receiving chain outputs received echo analog signals to a digital processing unit; the real-time imaging back end comprises a wireless signal receiver for receiving radar front-end signals and a DSP center processor for achieving distance measurement and imaging operation, a distance measurement unit for carrying out target distance measurement is connected between the information input end of the DSP center processor and the wireless signal receiver, and a SAR imaging unit for achieving target imagingis internally arranged in the DSP center processor. By means of the intelligent traffic detector based on the high-resolution radar, high-accuracy distance measurement can be achieved, imaging controlling can be clearly and accurately carried out, real-time monitoring of traffic road conditions is achieved, the structure of the system is simple, and power dissipation is low.
Description
technical field [0001] The invention relates to the field of radar systems, in particular to an intelligent traffic detector based on high-resolution radar. Background technique [0002] The monitoring of vehicles on the road is an important application of radar technology in the civilian field. In practical applications, there are mainly two types of simple speed measurement and comprehensive monitoring of vehicles. The former is mainly used on expressways or urban roads that require speed limits, and the measurement results are used as the basis for punishment; the latter is mainly used to monitor the progress of vehicles. Information such as direction, speed, vehicle length, and vehicle size. At this time, the radar is generally installed on one side of the road for side-view detection. [0003] The radar is installed on one side of the road, at a certain height from the ground, and is used to monitor the information of vehicles driving in the lane at a certain moment. ...
