A detection and tracking method based on monopulse radar in FSK mode applied in smart transportation systems

The traditional traffic speed measuring radar of FSK mode has inherent disadvantages that it cannot identify moving targets with the same speed. So in practical applications, we need to install the radar sensor in each lane for accurate measurements and tracking. In this paper, we put forward a new method to detect and track multiple targets using only one radar sensor by establishing a spatial model and analyzing characteristics of radar data between two adjacent frames. Meanwhile, we analyze the problems that may be encountered in practice when using this method and provide solutions. In the end, the feasibility of the method is verified by simulation.
