The aim of this paper is to present a method of adding an extended function to an existing HF sensor used in remote toll payment systems. The prime goal of a remote toll payment system is to establish a communication with an identification card inside vehicles moving under the beacon. The transaction payment is carried out when the vehicle is passing through the antenna beam. Our objective is to add an imaging function to classify the vehicles for traffic monitoring and verify that the size of the vehicles matches the information on the identification card. This problem has been previously presented and the purpose of this paper is to make improvements to the solution.
