Embodiment Construction

[0048] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.

[0049] A multi-band and multi-beam shipborne satellite meteorological information receiving and wind field detection system consists of a phased array antenna, satellite receiving equipment, and wind profile radar.

[0050] In terms of installation, it is divided into outdoor equipment and indoor equipment. Outdoor equipment mainly includes phased array antennas, and indoor equipment includes wind profile data receiver cabinets, satellite data receiver cabinets, monitoring and self-test cabinets, and control and application cabinets.

[0051] Among them, the satellite data receiver cabinet mainly integrates various modules of satellite receiving equipment, and is responsible for the demodulation and processing of satellite data, including filters, L...

Abstract

The invention relates to a multi-band multi-beam shipborne satellite meteorological information receiving and wind field detection system which is composed of a phased array antenna, a satellite receiving device and a wind profile radar, and the phased array antenna is used for transmitting satellite breath information to the satellite receiving device to achieve wind profile radar signal receiving and transmitting; an antenna array is formed by arranging unit antennas in a rectangular shape, and each unit antenna comprises an L1 frequency band, an L2 frequency band and a C frequency band andsupports various polarizations. The satellite receiving device is connected with the phased array antenna and used for receiving satellite data and completing receiving, unpacking, fast looking and storing of the satellite data, and the wind profile radar adopts a five-beam mode and is used for obtaining the air wind speed, the wind direction and Cn2 below the 5000-meter height of a ship surface and correcting the beam pointing and the wind direction and the wind speed in real time according to the ship attitude information. According to the scheme, multi-band multi-beam receiving of satellitemeteorological signals is achieved through the phased array antenna, and meanwhile signal receiving errors caused by the motion state are reduced.

Description

technical field [0001] The invention relates to the field of meteorological satellites, in particular to a multi-band and multi-beam shipborne satellite meteorological information receiving and wind field detection system. Background technique [0002] Meteorology and hydrology are important factors for victory in the battlefield. The battlefield is not only a confrontation of military forces, but also a competition in the detection and forecasting battlefield. This puts forward higher requirements for the mobility and all-round detection of the meteorological observation system. The navy is the only armed force that can operate in deep water and high altitude, as well as on land and sea. It needs to carry out in-depth and detailed hydro-meteorological support work. Perform detailed real-time detection. [0003] Meteorological satellites achieve global high-resolution observations and have all-day and all-weather capabilities. The meteorological satellite receiving and pro...
