Abstract

Embodiments of the invention provide a dual-band weather radar observation control method and system. A first trigger pulse is sent to a Ka-band transceiver in a dual-band weather radar; a second trigger pulse is sent to an X-band transceiver; a third trigger pulse is sent to a digital acquisition and storage device, so that simultaneous control of the ka-band transceiver, the X-band transceiver and the digital acquisition and storage device is realized. After a first sampling result and a second sampling result are obtained by the digital acquisition and storage device, a first control instruction is sent to a DSP board card, so that the DSP board card is controlled. The trigger pulses and the control instruction are sent to the ka-band transceiver, the x-band transceiver, the digital acquisition and storage device and the DSP board card in sequence, so that the ka-band transceiver, the x-band transceiver, the digital acquisition and storage device and the DSP board card are matched mutually to jointly complete observation work of the dual-band weather radar to obtain weather data.

Description

technical field [0001] The invention relates to the technical field of weather radar observation automatic control, and more specifically, to a dual-band weather radar observation control method and system. Background technique [0002] At present, the function of dual-band weather radar is to use the scattering effect of clouds and precipitation on electromagnetic waves to quantitatively detect the spatial position and distribution of clouds and rain, and meteorological parameters within the range of action, and to obtain the characteristics of the target's shape, phase state, and spatial orientation. . [0003] Take a typical X-band or Ka-band weather radar as an example. The X-band is mainly used to observe rainfall. This frequency band is the same as the working frequency band of the X-band weather and rain radar. Compared with the conventional S and C bands, the wavelength is shorter and the beam Narrow, high resolution, high signal-to-clutter ratio, which can reduce t...
