【Abstract】 The EIFOV model proposed by Lichti can only be used to calculate the horizontal EIFOV and the vertical EIFOV.How to calculate the EIFOV of any direction? To resolve this problem,the curve of the cut-off frequency is difined.The model of calculating the EIFOV of any direction and the model of evaluating the whole angular accuracy are derived.The nineTLS systems can be classified into three groups according to AEIFOV.The conclusion have directly significance on the angular resolution’s calculation and the scanning interval setting.更多还原
