Abstract
A robust blind deconvolution algorithm is proposed to cancel the sensor averaging effect caused by its wide detection area. The purpose herein is to retrieve features of the real signal that have been distorted by the averaging effect. The algorithm is applied to the case of an inductive loop detector. To perform the proposed algorithm, speed estimation is required. Vehicle reidentification rate from both raw signals and estimated real signals is compared. The sensor transfer function is calculated once from a learning phase; the estimated real signal is then computed in real time for the reidentification of each vehicle.
