This paper introduces the technical principle, satellite formation mode, baseline characteristics, wave position distribution and application mode of InSAR surveying and mapping satellite of "tianhua-2" distributed Interferometric Radar, and expounds the satellite's twin satellite following flight, working characteristics, data transmission, product use, etc. For the purpose of strengthening understanding and mastering the operation law of the InSAR surveying and mapping satellite, making good use of the side view angle, wave position interference and other characteristics to reasonably arrange the photography area, and doing a good job in task analysis, design and planning. And in the case of relatively certain equipment and resources such as load use, inter satellite link, ground transmission, etc., the requirements of high acquisition efficiency, good interference effect, wide area coverage, etc. are better achieved, so that the InSAR satellite of "tianhua-2" will play a greater role in its life cycle.<br>
