The three pass differential interferometry technology is an important means of ground deformation monitoring, which has been successfully used in the large ground deformation monitoring and research such as the earthquake, volcano activity, glacial drift, landslides, and city settlement etc. However the technology is affected by multiple errors in practical application, which have serious influence on the deformation monitoring precision. For spaceborne radar, this paper derives the error propagation coefficients of the baseline error, the phase error, the atmospheric delay error and the earth curvature error and other types of errors on the three pass differential interferometry base on the [three pass differential interferometry] principle, and analyses the characteristics of these errors, finally discusses the influence rules of the errors on three pass differential interferometry.

Artykuł dotyczy zagadnienia trójpasmowej interferometrii różnicowej, jako narzędzia do monitorowania deformacji gruntu w przypadku trzęsień ziemi, aktywności wulkanicznej itp. Na potrzeby radarów znajdujących się na orbicie kosmicznej, wyznaczono współczynnik propagacji błędów, typowych w tego rodzaju pomiarach (błąd fazowy, opóźnienie w atmosferze, zakrzywienie powierzchni Ziemi). Opisano mechanizm wpływu obecności tych błędów i uchybów na wynik działania metody.
