The launch of the Sentinel-1 satellites, providing high-quality SAR images in C-band (5.405 GHz) at a very high temporal frequency (every 6 days until the end of 2021). The advancements both in computing capacity and processing algorithms enabled the determination of surface displacements on regional and even continental scale. C-band based InSAR processing has many limitations however, when applied in temperate regions. Seasonal change in soil moisture, vegetation foliage, surface coverage (snow cover) and agricultural activities (plowing, seeding, crop development) can all lead to loss of coherence and consequently loss of deformation information. These factors can render the determination of surface motions very difficult in areas where the velocity of these motions is low (< 1-2 mm / year). In this contribution the authors wish to present results of InSAR processing applied to an area (Hungary in Central Europe) where the mentioned limitations (temperate region, low expected displacement velocities) are present. Approximately 250 Sentinel-1 images, both ascending and descending direction, between 2016 and 2021 were processed covering the area of interest. The images were processed using the Gamma software package (https://www.gamma-rs.ch/software) with both Persistent Scatterer (PS) and Small Baseline (SBAS) InSAR processing methods. We present the results of the two processing strategies, discuss the advantages and shortcomings, and provide an outlook on future work, with recommendations on how to plan and execute such large-scale analysis.

The attempts to apply InSAR technologies using archive and Sentinel-1 data practically failed on the most intensive landside areas (“Vár” and “Szent János” hills), where proper persistent or distributed scatterers were not found. Our concept solved this problem, where the Simple Look Complex (SLC) images are used to interpolate the movements between two GNSS network observations using the integrated benchmarks and the method of Kalman-filtering. Since the InSAR line-of-sight (LOS) changes are barely sensitive to the north movements, this information is essentially provided by GNSS measurement alone, moreover, the GNSS measurements are used to: a) identify the benchmarks, b) detect the unwrapping errors and missing cycles and c) provide the boundary values of Kalman-filtering.After the installation of benchmarks three GPS observations were carried out and 69 ascending and 61 descending Sentinel-1 A and B images were processed. The data processing properly indicated the general movement history, which fit the curves of former geodetic observations, as well. The dense data points of the East and Up (vertical) components made possible more detailed geomorphologic interpretations of the ongoing process between two GPS observations. During the investigated periods the deceleration of movements was experienced, however, the deceleration of the dormant state needs the continuation of the monitoring.
