Embodiment Construction

[0078] A detection method for Antarctic subglacial water based on the morphological characteristics of the basement signal, which is characterized in that multiple identification indicators are integrated to obtain the possibility of water at the basement interface, instead of using multiple empirical thresholds to determine the probability of water at the basement interface Multiple indicators make hard judgments, which will greatly reduce the uncertainty of detection.

[0079] Step 1. Radio echo sounding data preparation

[0080] The radio echo sounding data used are the data products of the Multi-channel Coherent Radar Sounder (MCoRDS) provided by the Center for Remote Sensing of Ice Sheets (CReSIS).

[0081] Step 2. Construct the standard to describe the horizontal morphological characteristics of the base signal

[0082] Step 2.1, Obtaining Ice Bed Elevation Data

[0083] Step 2.2, get three indicators that can describe the horizontal morphological characteristics

Abstract

The invention discloses an antarctic subglacial water detection method based on morphological characteristics of base signals. The method comprises the following steps: 1, preparing radio echo sounding data; 2, constructing a standard for describing the horizontal morphological characteristics of the substrate signal: 2.1, acquiring elevation data of an ice bed, 2.2, obtaining three indexes capable of describing horizontal morphological characteristics; and 2.3, constructing a standard, specifically, in order to highlight the position with strong elevation horizontal morphological characteristics of the ice bed, defining the standard for describing the elevation horizontal morphological characteristics of the ice bed in the specification; 3, constructing a standard for describing the vertical morphological characteristics of the substrate signal: 3.1, acquiring base signal data, 3.2, obtaining five indexes capable of describing vertical morphological characteristics: (1) responsivity, (2) degree of symmetry, (3) thin height, (4) thinness, and (5) the deviation degree of the substrate interface, and 3.3, constructing a standard; and 4, obtaining the possibility that the substrate has water under ice: 4.1, conducting preliminary possibility judgment, and 4.2, conducting final possibility judgment and classified display.

Description

technical field [0001] The invention relates to a method of processing radio echo sounding data in the Antarctic region by using the morphological characteristics of the base signal, constructing multiple indicators that can describe the morphological characteristics of the base signal, and jointly using these indicators to obtain the possibility of water in the base Thematic information extraction method. Background technique [0002] The water under the ice sheet in the polar regions is a very important natural phenomenon. It is an important hub of the subglacial hydrological network. It will accelerate the sliding and disintegration of the overlying ice sheet and play a decisive role in the rise of sea level and the change of climate environment. role. Therefore, the location of subglacial water is a very favorable data support for subglacial hydrology research, water potential prediction of water network, and ice flow change analysis. Then detecting the location of sub...
