Transducers for ultrasound in air suffer from high production tolerances. High-resolution imaging therefore requires calibration of the sensor elements.
We develop a new signal model for calibration based on a prototype air-coupled ultrasonic phased array designed and assembled by the Measurement and Sensor Technology Group at TU Darmstadt. Your task is to evaluate the corresponding estimation of model parameters and derive the performance bound of each estimator.
