Embodiment Construction
[0015] Concrete detection method of the present invention is as follows:
[0016] First, select N points in the tornado-prone area, and the distance between adjacent points is 60-100 kilometers. Every three points form a triangle (preferably an equilateral triangle) and arrange N mobile weather radars at these points respectively. During the time when the tornado did not occur, every three adjacent radars made joint observations to obtain three-dimensional detection data. see figure 1 As shown, it is a layout diagram when N=6.
[0017] The combination and scanning sequence of coordinated observation are: (1) radars 1, 3, and 4 simultaneously scan the triangle formed by 1, 3, and 4; (2) radars 1, 2, and 4 simultaneously scan the triangle formed by 1, 2, and 4; ( 3) 3, 5, 4 radars simultaneously scan the triangle formed by 3, 5, 4; (4) 4, 5, 6 radars simultaneously scan the triangle formed by 4, 5, 6. Then go back to (1) and repeat.
[0018] When a tornado occurs, if figur...
