Topographic phase is a key parameter in the Random Volume over Ground forest model. Its estimation error influences the estimation accuracy of other forest parameters. Therefore, the error analysis and error control in topographic is necessary to obtain the accurate forest parameters. This paper analyzes the main error sources in topographic phase and provides a method to estimate the possible error range. To examine the proposed method, the error analysis is applied on the results of ESAR L band forest data.
