description The invention relates to application of microwave remote sensing in the field of forests and discloses a polarimetric synthetic aperture radar interferometry (POLInSAR) vegetation height inversion method based on complex field adjustment theory. The complex field adjustment theory and a physical model for POLInSAR vegetation height inversion are organically combined by the method. The method comprises the following steps of: I, performing registration on obtained complete polarization data of N scenes to obtain M baseline interference pairs; II, performing polarized interference on the M baseline interference pair to obtain M*P interference fringe patterns, and estimating corresponding complex coherences of the M*P interference fringe patterns; and III, working out a vegetation height hv based on complex field adjustment computation. The POLInSAR vegetation height inversion method based on the complex field adjustment theory is visual in principle, is easy to realize programming and extension, is a steady and
