Application of Model-Based Estimation to Time-Delay Estimation of Ultrasonic Testing Signals
Time-Delay-Estimation (TDE) has been a topic of interest in many applications in the past few decades. The emphasis of this work is on the application of model-based estimation (MBE) for TDE of ultrasonic signals used in ultrasonic thickness gaging. Ultrasonic thickness gaging is based on precise measurement of the time difference between successive echoes which reflect back from the back wall ...
متن کاملTime delay estimation and signal reconstruction using multi-rate measurements
This paper considers the problem of fusing two low-rate sensors (e.g., microphones) for reconstructing one highresolution signal when time delay of arrival (TDOA) is present as well. We show that under certain conditions the phase of the cross-spectrum-density of lowrate measurements becomes independent of the signal in the high-rate front end of the system. We then utilize this fact to demonst...
متن کاملMultiple-Model Adaptive Estimation for Measurements with Unknown Time Delay
If a sensor requires finite processing and communication time, then the current sensor reading actually corresponds to the states of a vehicle at some point in the past. At the sensor fusion algorithm, it is expected that large errors may accumulate over time if we simply ignore the fact that the sensor measurement is lagged. Over several decades, the Kalman filter based compensation techniques...

15 صفحه اولTime - Delay Estimation ∗
An important signal parameter estimation problem is time-delay estimation. Here the unknown is the time origin of the signal: s (l, θ) = s (l − θ). The duration of the signal (the domain over which the signal is de ned) is assumed brief compared with the observation interval L. Although in continuous time the signal delay is a continuous-valued variable, in discrete time it is not. Consequently...
