摘要

Nonlinear theory of Doppler reflectometry is generalized to the case of the cylindrical plasma geometry, which takes into account the plasma poloidal curvature. The registered signal power is calculated taking into account possible curvature of the probing antenna wavefront. The spectrum shift is analyzed and shown to correspond to the poloidal velocity specifically averaged over the probing wave propagation region with the weight function reflecting the geometry influence.
