<p>PURPOSE:To perform automatic synthesis due to the optimum data by calculating beam altitude at every mesh on the basis of the use elevation and height of radar and comparing the same with the altitude of land surface at every mesh to automatically select the optimum data. CONSTITUTION:A beam altitude calculation part 6 refers to a radar height data base 5 on the basis of the input of the use elevation of radar to read the height of the radar wherein the use elevation is inputted and subsequently calculates the beam altitude at every mesh on the basis of the height and use elevation of the radar to input the same to an optimum data selection part 8 along with the beam altitude of the adjacent radar calculated in the same way. The selection part 8 refers to a land surface altitude data base 7 to read the altitude of land surface at every mesh and performs the comparison of beam altitude and the altitude of land surface at every mesh to synthetically judge the respective data and automatically selects the optimum data in input radar data 1 in real time to send out the same as output radar data. By this method, the use elevation of the radar is indicated to automatically perform the synthesis by an optimum data.</p> |
