Radar base data acquisition method and device

The invention provides a radar base data acquisition method and device and is applied to calculation equipment. The method comprises steps that in-phase data and orthogonal data of at least one distance database which correspond to the radar echo and are scanned by a weather radar are acquired; for each distance database, a polarization mode when the weather radar scans the distance database is determined according to the in-phase data and the orthogonal data of the distance database; the preset base data calculation strategy corresponding to the determination result is searched according to the determination result, the in-phase data and the orthogonal data of the distance database are subjected to data processing according to the searched base data calculation strategy, and weather radarbase data corresponding to the distance database is obtained. The method is advantaged in that cost is low, upgrade and replacement difficulty is low, and radar base data acquisition operation can beperformed to weather rada
