Problems solved by technology

In the prior art, the DEM and DOM are usually obtained by aerial photogrammetry, which has the advantages of high efficiency, high precision and low labor intensity, and is mainly carried out by a full digital photogrammetry workstation, but the aerial photogrammetry method When acquiring data, it is necessary to consider the influence of light and weather factors, which are restricted by conditions such as clouds, fog, rain, dust, and light, and are subject to aviation control, so the cost is relatively high; when using aerial photogrammetry to obtain DEM, the same There will be elevation anomalies between different images in the flight belt or adjacent images between different flight belts, which will affect the overall consistency and continuity of the acquired DEM

Abstract

The invention discloses a rapid real-time processing method and system for airborne InSAR data, and relates to the technical field of InSAR data processing, and the method comprises the steps: the coordinate information of a ground control point in a measurement region is uploaded before takeoff; the carrier aircraft emits electromagnetic waves and receives ground echo scattering data, airborne InSAR data information is generated according to the echo scattering data and is rapidly processed in real time, and then a DEM graph and a DOM graph which accord with the national basic scale are transmitted to a ground station or a personal user in real time before the carrier aircraft lands. According to the invention, ground control point information is uploaded before takeoff, electromagnetic waves are emitted through the aerial carrier and ground echo scattering data are received, rapid, real-time and automatic data processing can be carried out on the carrier aircraft, and DEM and DOM meeting the national standard scale can be transmitted to a ground workstation or a personal user before or after the aircraft lands, so that the data processing and transmission efficiency can be improved, and the user requirements can be better met.

Description

technical field [0001] The present invention relates to the technical field of InSAR data processing, and more specifically, to a fast real-time processing method and system for airborne InSAR data. Background technique [0002] A digital elevation model (Digital Elevation Model, DEM) is a physical ground model that describes the spatial distribution of regional geomorphology, is a virtual representation of geomorphology, and uses a set of ordered numerical arrays to represent ground elevation. Digital Orthophoto Map (DOM) is a digital orthophoto dataset generated by using DEM to perform orthorectification, edge joining, color adjustment, mosaicking, and cutting according to a certain range of aerospace images. [0003] InSAR (Interferometric Synthetic Aperture Radar; abbreviation: interferometric radar measurement) technology originated in the United States, and has been continuously improved and matured in developed countries in Europe and the United States, and its applic...
