Abstract

A digital technique for high-resolution estimation of occurrence time of detected events is presented. The method achieves timing precisions well below the sampling time interval through a nonrecursive processing strategy. Due to linearity of the procedure, the processing runs online, and the architecture has been implemented in a configurable field programmable gate array (FPGA) device with a very limited resource burden. The method has been validated through processing of simulated and measured data and a full experimental assessment of the technique in an acquisition and processing digital setup for different operative conditions is at present going on.
