The paper is devoted to the study of displacement measurement accuracy by radar interferometry method using corner reflectors and application of space radar images in different frequency bands. A wide range of synthetic aperture radar (SAR) spacecrafts providing images in different frequency bands is currently available on the Earth remote sensing market. Use of data from several spacecrafts may significantly increase operational efficiency, accuracy of measurements and reduce risks related to the possible unavailability of survey from one or another SAR spacecraft. The technology of differential interferometry using corner reflectors allows to avoid decorrelation of radiofrequency signal in X and C-bands due to vegetation, precipitation etc. However, depending on the frequency band of observation, specific requirements are applied to the sizing and shape of corner reflectors, required spatial resolution of images etc. This paper evaluates the contribution of different parameters in the displacement measurement accuracy and gives recommendations for improving displacement measurement accuracy by radar interferometry method using corner reflectors.
Keywords: synthetic aperture radar (SAR), radar interferometry, Earth remote sensing, differential interferometry, Earth’s surface subsidence monitoring, corner reflector
