    Classification of agricultural land use and derivation of biophysical parameter
using SAR and optical data
    (Informatik in der Land-, Forst- und Ernährungswirtschaft 2017, 2017) Knöfel, Patrick; Dahms, Thorsten; Borg, Erik; Conrad, Christopher
    Agricultural monitoring is essential for global issues, which can be reflected by the terms of food security and ensuring ecosystem services. Due to the high spatial and temporal resolution of the remote sensing sensors enormous potential for precision farming has been worked out in cooperation between science and the private sector. However, the quality of field specific yield estimations, for instance, is highly influenced by the accuracy of the underlying information like land use, plant development, and stress indicators. Thus, particular knowledge about the accuracy of all the relevant indicators is crucial for agricultural monitoring. The chair of remote sensing at the University of Wuerzburg has gained a lot of expertise in this context by working on their three latest ongoing projects with agricultural focus. Within the framework of these projects, a classification and assessment tool with graphical user interface (MELanGe) was developed, which can be used for land use mapping and biophysical parameter derivation.

    A multi-agent concept for multistatic sonar
    (INFORMATIK 2010. Service Science – Neue Perspektiven für die Informatik. Band 2, 2010) Ehlers, Frank
    In this paper we present a novel and relevant application for multiagent systems which is to implement autonomy for Multistatic Sonar. Multistatic Sonar is used in Antisubmarine Warfare and exploits multiple aspects on the target generated by multiple acoustic sources and receivers. We propose to use a team of unmanned underwater vehicles starting with search operations as covert receivers and then switching to pursuit operations as actively communicating multistatic receivers. This results in a safe, persistent and efficient surveillance system. With the help of a simulation setup, we explain what are the specific challenges related to the Multistatic Sonar setup. These challenges are mainly related to the highly nonlinear measurement model and to communication constraints. We then briefly outline a potential “baseline” solution for the overall system architecture capable to face these challenges.
