By solving the three-dimensional time-dependent Schrödinger equation, we have theoretically investigated the variation of photoelectron spectroscopy and angular distribution of hydrogen atom with carrier envelope phase (CEP) under the resonant condition. The results show that the intensity of photoelectron spectroscopy is strongly dependent on CEP near the resonant position; and the angular momentum quantum number of resonant initial-ionized state can be determined by further analyzing each partial wave. In addition, we can detect the information of initial phase of multi-cycle pulses with high accuracy by utilizing the information of angular distribution of photoelectron.
