[0052] The position and volume scanning mode of the networked weather radar affect the coverage and landing area of the three-dimensional space scale, and affect the acquisition of space atmospheric scanning information. At present, the basic scanning methods of radar VCP are mainly divided into two types: clear sky mode and precipitation mode, usually including 9 volume scanning modes, namely: VCP32, VCP31, VCP21, VCP11, VCP12, VCP121, VCP211, VCP212 and VCP221, among which, The scanning mechanisms of VCP211, VCP221, and VCP212 correspond to those of VCP11, VCP21, and VCP12 respectively. The difference is that the phase encoding algorithm is used on the two elevation angles of the lower layer to improve the detection of unambiguous speed.
[0053] For the clear sky mode, there are mainly two types, VCP31 and VCP32, including 5 elevation angles, and the scanning time is about 10 minutes. The pulse width of VCP31 is 4.7us, and the PRF is about 322Hz; while the pulse width of ...
