| description | The embodiment of the invention relates to a real-time distance measurement ambiguity resolution algorithm under large-range maneuvering. The method comprises the following steps: performing defuzzification processing on an initial point, and calculating a first real distance and a whole cycle number; next data to be defuzzified is taken, and data interruption judgment is carried out; if not, calculating an increment accumulated value and a second real distance; and comparing the first real distance with the second real distance to obtain an actually measured distance. According to the embodiment of the invention, on one hand, the problem of real-time ambiguity resolution calculation in the large-range continuous maneuvering process of the spacecraft can be effectively solved; on the other hand, due to the fact that increment and accumulation calculation is carried out, only the ambiguity resolution result of the current data is affected after interference of abnormal data, and subsequent data ambiguity resol |
