Abstract
A method of measuring the CW pulse signal phase difference is proposed, which is able to measure the phase difference between the difference frequency wave of parametric array and the small amplitude wave with the same frequency. The method is verified by simulation experiment. The factors influencing the measurement results ware discussed, such as the sampling rate, noise and sensor position. The numerical analysis results show that the proposed method can effectively measure the phase difference between the difference frequency wave of parametric array and the small amplitude wave with the same frequency.
