摘要

Topic Does not transmit the ultra wave equal to the number of ensembles repetitively classified by scan line and decrease of frame rate the device and the method where it can form dying and TDI are disclosed also the te.SolutionsAccording to this invention, it transmits the beam with non consecutive system, corresponds to each transmission of the transmission beam and in the increase data of increase direction of the scan line index and the decrease data of the reduction direction grouping it does the plural reception beams which are received. It executes autocorrelation the data classified by group by increase of the scan line index and decrease direction, multiplying weightings the autocorrelation value for the increase and decrease data group vis-a-vis respectively, summing up the value which is obtained, it seeks average phase. Within speed value, power value and the dispersed value which correspond to this average phase at least outputting one, it forms TDI. Selective figure Figure 4
