title: Estimator for reflective delay line-type SAW sensors.
abstract: This correspondence presents an estimator for reflective delay line-type surface acoustic wave (SAW) sensors. The estimator is derived from an analytical model and its range of validity is discussed. The proposed estimator enables simultaneous access to several SAW sensors with time-orthogonal responses and it can be implemented in a computationally efficient way utilizing the fast Fourier transform algorithm. The estimator is experimentally verified and its performance is compared with that of a reference estimator.
