The fundament of flat terrain phase effect and its removal are stated. The interferogram consists, for each pixel, of the complex conjugate product of two SAS images directly, which cant reflect the actual terrain change. The general phase trend in range can be considered as the phase generated by an ideally flat terrain and is often subtracted from the interferogram before further processing.

the digitized mapping technique is to combine the field data collection system with the computer assisted mapping system in surveys by computer technology.it aims to realize the information collected and processed digitally and automaticaity.the digitized mapping technique can cut short the working time,lighten the labor intensity and enhance the precision of the productions.the system consists of three parts,such as data input,data processing and data output.the survey-record digitized mapping technique is widely used in the digitized mapping working pattern.for its superiority over traditional plane-table mapping in accuracy and efficiency,the large scale digital mapping is becoming more and more popular.compared with traditional analogue mapping,digital mapping has more quality control pivotai points,and its contents and methods are more complex.with the appearance of new technology gps ,the coordinate of different levels controlling points may be surveyed in high precision and it has been applied widely in topographic survey.the operation process of gps electronic tachometer is introduced and its application in topographic survey is br

A technique of massive scale data management and attemperation based on viewpoint. This algorithm effectively changes massive scale terrain into large scale ones to handle. Utilising the continuity of the viewpoint movement and the relativity of fore-and-aft frames, it manages and attempers the terrain data leading to data decrease in a large range. This algorithm solves the problem of the rendering rate, and realizes a rapid real-time ramble in massive scale terrain scenes.

This paper studys the terrain following for low penetration aircraft ,and establishes the model of ALCM's clobber probability based on the Butterworth terrain model . It simulates much of the computation of its clobber probability under typical cruise conditions and analyzes those simulation results deeply. The control system is designed based on the lobber probability simulation result,and the reasonable control data are given.According to those research,the digital terrain following simulations are given .
