Abstract

The invention relates to a microwave remote sensing soil moisture monitoring system and a monitoring method thereof. The monitoring system comprises a detection arm, a signal receiving antenna and a thermal infrared thermometer carried on the detection arm, a microwave detection system electrically connected with the signal receiving antenna and the thermal infrared thermometer, and a data processing device electrically connected with the microwave detection system. According to the monitoring method, a data analysis treatment system in the data treatment device performs the real-time synchronous treatment according to brightness temperature data acquired by the microwave detection system and physical temperature data on the surface of soil obtained by the thermal infrared thermometer to accurately evaluate soil moisture information. The microwave remote sensing soil moisture monitoring system and the monitoring method thereof provided by the invention obtains soil microwave radiation signals by using a passive way, has a simple working model, high precision, and high efficiency, and is not limited by the observation frequency.

Description

technical field [0001] The invention relates to the technical field of microwave remote sensing, in particular to a microwave remote sensing soil moisture monitoring system and a monitoring method thereof. Background technique [0002] An important parameter in the fields of hydrology, meteorology, and agricultural science research is soil moisture, which also plays a very important role in today's agricultural development. Accurate and real-time soil moisture monitoring and inversion are of great significance in the fields of agricultural science, such as the rational use of water resources, agricultural irrigation, and drought and flood disaster forecasting. Forecasting and other aspects have a great impact. In agricultural production, the losses caused by drought disasters are very serious every year. Preparing to know the soil moisture situation is conducive to taking corresponding countermeasures and measures in time to reduce the losses caused by agricultural producti...
