Webb30 juli 2024 · The theoretical accuracy of the system can reach 7 cm. However, due to the effect of residual calibration error and data processing-induced error, the final … Synthetic aperture radar (SAR) is a form of radar in which sophisticated processing of radar data is used to produce a very narrow effective beam. It can be used to form images of relatively immobile targets; moving targets can be blurred or displaced in the formed images. SAR is a form of active remote sensing – the antenna transmits radiation that is reflected from the image area… Webb20 mars 2024 · Objectives: Based on TerraSAR/TanDEM-X satellite-based single-polarization InSAR data, we studied the effects of estimation algorithm selection and coherence coefficient calculation method on the accuracy of forest height estimation results based on InSAR technology at different spatial scales.
