Soil physical property classification recognition method and device based on geological radar

Abstract

The invention discloses a soil physical property classification recognition method based on geological radar. The method includes the data preprocessing step, the soil physical property information extraction step, the neural network training step and the soil physical property classification recognition step, wherein in the data preprocessing step, digital signals acquired by the geological radar are de-noised and filtered; in the soil physical property information extraction step, characteristic data for representing soil physical properties are extracted from data after the data preprocessing step; in the neural network training step, the characteristic data are used for training a neural network as a data set for training the neural network, and a mapping result corresponding to the characteristic data is obtained; in the soil physical property classification recognition step, the characteristic data to be recognized for representing the soil physical properties are input the trained neural network, and the classification of the soil physical properties is recognized according to the mapping result of the neural network. The invention further discloses a soil physical property classification recognition device based on the geological radar. Through the soil physical property classification recognition method based on the geological radar, the physical properties of soil of a region to be detected can be fast and accurately recognized based on radar detection data.

Description

technical field [0001] The invention relates to the field of detection technology, in particular to a method and device for identifying soil physical properties based on geological radar. Background technique [0002] Soil physical properties refer to soil physical properties, such as soil water content, soil texture, soil porosity, etc. Taking soil water content as an example, soil can be regarded as different categories according to the value of soil water content. Mastering the types of soil physical properties is beneficial to environmental protection, engineering planning and construction, etc. [0003] Geological radar technology is a science of underground target detection by transmitting high-frequency pulsed electromagnetic waves (frequency range 106-109Hz). The basic principle is: the transmitter transmits pulsed electromagnetic wave signals through the transmitting antenna. When detecting a target, a reflected signal is generated. The direct signal and reflecte...

Problems solved by technology

However, in the face of relatively complex geological conditions, due to the complex and changeable underground medium, the echo signal often has the characteristics of time-varying, non-stationary and random, so it is difficult to correctly explain the appearance characteristics after being complicated, and also because Therefore, it is impossible to accurately and quickly detect the physical properties of the soil only by relying on ground radar detection
