Problems solved by technology

For example, in the microwave band, the specific emissivity of water is 0.4, while the specific emissivity of ice is 0.99. At room temperature, the brightness temperature difference between the two is 100K, which is easy to distinguish. In the infrared band, the specific emissivity of water is 0.96, the specific emissivity of ice is 0.92, the difference between the two is very small, and it is not easy to distinguish

Abstract

The invention discloses a sea ice microwave remote sensing monitoring system which comprises a GNSS signal source, an RADARSAT signal source, a GNSS-R receiver, a mobile platform, a platform control system and a data receiving and processing system; the GNSS signal source provides an L-band signal; the RADARSAT signal source provides a backscattering signal; the GNSS-R receiver receives a direct signal of the GNSS signal source and a forward-scattering signal which enters a sea ice surface and is scattered; the data receiving and processing system receives the forward-scattering signal and the backscattering signal, and processes and analyzes the received signal; and the platform control system controls the movement of the mobile platform. The sea ice microwave remote sensing monitoring system realizes the innovation of traditional monitoring means, can work all day long in all weathers, simultaneously has stronger permeability because the GNSS-R works in the L-band with quite long wavelength, and can realize the low-cost and high-efficiency monitoring to sea ice.

Description

technical field [0001] The invention relates to a sea ice monitoring technology, in particular to a sea ice microwave remote sensing monitoring system. Background technique [0002] Sea ice disaster is one of the most important natural disasters, which affects the production and life of human beings such as marine transportation and marine resource development. However, the extraordinary sea ice disaster in Bohai Bay that broke out in January 2010 once again brought sea ice disasters into the focus of attention, and further It has deepened the sense of responsibility and mission of scientific researchers in the field of remote sensing for sea ice monitoring and research. [0003] Remote sensing technology is an important means of sea ice monitoring, but the current remote sensing monitoring methods have certain limitations. For example, optical and infrared remote sensing are limited to weather conditions and cannot work around the clock; microwave remote sensing overcomes ...
