Abstract

Aiming at improving the speed precision especially when there are more than one targets run through radar speed instrument at one time, we discuss the relation between the key performance parameters and speed precision as well as speed resolution. Then the main defects of the current traffic speed radars are analyzed and improvement measures are provided. Finally we provide a solution for multi-target circumstance. The solution uses STFT to improve time-frequency resolution. The simulation results show that the speed error decrease to less than when adopting the algorithm proposed in the paper.
