In a perspective to develop an inversion approach for estimating surface soil moisture of crop fields from Sentinel-1/2 data (radar and optical sensors), the Water Cloud Model (WCM) was calibrated from C-band Synthetic Aperture Radar (SAR) data and Normalized Difference Vegetation Index (NDVI) values collected over crops fields and grasslands. The soil contribution that depends on soil moisture...

The objective of this study was to analyze the sensitivity of radar signals in the X-band in irrigated grassland conditions. The backscattered radar signals were analyzed according to soil moisture and vegetation parameters using linear regression models. A time series of radar (TerraSAR-X and COSMO-SkyMed) and optical (SPOT and LANDSAT) images was acquired at a high temporal frequency in 2013 ...

Humanitarian demining is a very urgent and important task for many countries and many techniques are proposed for its solution [1]. We have developed a bistatic GPR system using an Optical Electric Field Sensor (OEFS) as a receiver for landmine detection [2]. This system has two unique features, one is that it is a bistatic radar and the other one is to use a OEFS as a receiver. Therefore, it i...

[1] This paper describes an algorithm for inferring cirrus cloud top and cloud base effective particle sizes and cloud optical thickness from the Moderate Resolution Imaging Spectroradiometer (MODIS) 0.645, 1.64 and 2.13, and 3.75 mm band reflectances/ radiances. This approach uses a successive minimization method based on a look-up library of precomputed reflectances/radiances from an adding-d...

The Remote Sensing Centre (RSC) of the Institute of Geodesy, Cartography and Remote Sensing (FÖMI) has provided many services in the past 30 years to the Ministry of Agriculture and Rural Development (MARD) and the Ministry of Environment and Water (MEW). FÖMI also accumulated operational experiences in the applications of remote sensing. The unique methodology of the operational Crop Monitorin...

Incoherent scatter radars (ISR) are versatile instruments for continuous monitoring of ionisation processes in the Earth's atmosphere. EISCAT, The European Incoherent Scatter facility has proven e€ective also in meteor studies. The time resolution of the radar can be reduced to a few milliseconds, sucient to resolve the passage of individual meteors through the narrow ISR beam. Methods for gro...

[1] The ages of large impact craters on the Moon can be estimated by measuring the size-frequency distribution of smaller craters superimposed on their ejecta, but applying this method to individual craters under 3 km in diameter remains difficult due to their limited areal extent. The ejecta blankets of fresh lunar impact craters are expressed as halos of optical and radar bright material that...

in this article, a new method for fusion of high resolution optical and radar data for higher quality road extraction is presented. the proposed methodology consists of two stages of separate road detection from each data and knowledge based fusion of results. neural networks are separately applied on high resolution ikonos and terrasar-x images for road detection, using a variety of texture pa...

The long-range goal of this research is to extend the scientific basis for extracting environmental information regarding the nearshore ocean from remote sensing data. In particular, we seek to quantify how both optical and remote sensors image the breaking of waves in shallow water. OBJECTIVES The objectives of this project are as follows: 1. Assemble a marine radar wave observation system sui...
