The electron dynamics and radiation characteristics of nonlinear Thomson scattering in a linearly polarized intense few-cycle laser pulse are investigated. In the few-cycle laser pulse, the electron dynamics depends sensitively on the carrier-envelope (CE) phase of the driving pulse. The Thomson scattering radiation also shows many remarkable phase-sensitive characteristics. For most CE phases, the left-right symmetry of radiation angular distributions is broken down and the well-known fourfold symmetry is reduced to a twofold symmetry. The radiation spectra also depend on the CE phase and show a left-right asymmetry for most CE phases. These phenomena can be attributed to the properties of the few-cycle pulse and become less evident with increasing duration of the driving pulse. Moreover, possible ways to observe these phenomena are suggested. In addition, we propose that phase-sensitive characteristics of nonlinear Thomson scattering can be utilized to determine the CE phase of the intense few-cycle pulse.
