A method of interrogating an acoustic wave sensor comprises transmitting, by an interrogator, an interrogation radiofrequency signal to the acoustic wave sensor by way of a transmission antenna, receiving, by the interrogator, a response radiofrequency signal from the acoustic wave sensor by way of a reception antenna, and processing by a processing means of the interrogator the received response radiofrequency signal to obtain in-phase and quadrature components both in the time domain and the frequency domain, determining by the processing means perturbations of the obtained in-phase and quadrature components both in the time domain and the frequency domain and determining by the processing means a value of a measurand based on the detected perturbations.
