The precise three dimension coordinate B, L, H can be obtained with GPS technique. It must be transformed into users needed coordinates, which has been applied widely in this field.
The proposed scheme only requires three single-mode cavity fields and one classical field, thus it is easier to be realized in experiment by using cavity QED technique.
该方案装置简单，仅需三个单模腔场和一个经典场，且在制备过程中腔场可始终处于真空态。

Wind field retrieval from dual-Doppler radar data USES synthesis technique, and the vertical velocity is obtained by using continuity equation, then the three-dimensional wind fields are retrieved.
