Embodiment Construction

[0030] The technical solutions of the present invention will be described in more detail below in connection with specific embodiments, but the scope of the invention is not limited to the following.

[0031] like figure 1 As shown, a multi-function phased array antenna for satellite broadcast data receiving and wind profile, including antenna cover, antenna array, TR component, mounting frame, feed network, wave control power board, combination navigation, etc. . The multi-function phased array antenna mainly receives meteorological signals broadcast in meteorological satellite L-band (1670-1710 MHz, hereinafter referred to as L1 band), and downconverts, providing input signals for satellite intermediate frequency receivers; emission L-band (1280-1300MHz, below The high power pulse signal called the L2 wave section, receives the turbulent reflection L2 band echo signal and downconverts, provides an input signal for the wind profile radar digital intermediate frequency receiver. S...

Abstract

The invention relates to a multifunctional phased array antenna for satellite broadcast data reception and wind profile measurement, including radome, antenna array, TR assembly, installation frame, feeding network, wave control power supply board, integrated navigation and other parts , a multi-functional phased array antenna used for satellite broadcast data reception and wind profile measurement, through a common-aperture phased array antenna to complete satellite weather broadcast data reception and wind profile radar signal transmission and reception, both can be carried out at the same time, independent of each other interference. The multifunctional phased array antenna is mainly used to receive my country's independent meteorological satellites, supplemented by receiving foreign meteorological satellites; the signal transmission power used for wind profile measurement is not less than 2kW, which meets the needs of boundary layer wind profile detection.

Description

Technical field [0001] The present invention relates to the field of antenna, and more particularly to a multi-function phased array antenna for satellite broadcast data reception and a wind profile measurement. Background technique [0002] High-speed accompanying meteorological protection is a strong guarantee for rescue disaster relief, special plane escort, information operation, etc., such equipment uses vehicles, ships as platforms, integrated various meteorological observation systems, integrated foundations, empty groups, and Tianji observations Meteorological hydrological information. With the increase of meteorological protection, the equipment installed by the vehicle, the ship and the ship has more and more equipment, the installation position is very crowded, and the electromagnetic environment is more complicated. Inventive content [0003] It is an object of the present invention to overcome the shortcomings of the prior art, providing a multi-function phased arra...
