Welcome to IHE

The Institute of Radio Frequency Engineering and Electronics (IHE) is an institute within the Faculty of Electrical Engineering and Information Technology of the division 3 Mechanical and Electrical Engineering of Karlsruhe Institute of Technology (KIT). 

The research areas of IHE are oriented towards novel systems in the microwave technology, with goals of realizing these novel systems for use in the industry or commercially.   

The major research subjects are:

In the courses offered by IHE, fundamental concepts as well as application-based knowledge are taught. Besides lectures, tutorials and labs, the students will learn through case studies and to apply their knowledge in practical situations. Early on students will be exposed to practice-oriented projects with project partners in the industry or research centers.

In their most recent decadal assessment (Earth Application from Space, 2007) of Earth science space missions the U.S. National Research Council identified the Precipitation and All-weather Temperature and Humidity (PATH) mission as one of ten recommended medium cost missions. Based on the NRC’s outlined goals, PATH would have the unique capability of providing all-weather temperature and moisture soundings and cloud and raincell imagery at spatial scales comparable to AMSU-A/B or ATMS, but at sub-hourly temporal resolution. The essential need is to provide the atmospheric penetrability and spatial resolution of operational microwave sensors but with temporal resolution commensurate with the natural rate of evolution of convectively driven weather. This seminar will focus on the merits of a constellation of passive microwave sounding and imaging CubeSats for achieving PATH goals from the multiple viewpoints of calibration accuracy, data assimilation and global sampling, downlink capability and latency, and orbital lifetime and launch availability. Microwave spectral imagery at 50, 118, and 183 GHz with spatial resolution of ~10-30 km and temporal resolution of ~15-60 minutes from such a fleet could be expected to significantly enhance forecasting of mesoscale convective weather and hurricane rain band evolution, along with provide valuable temporal gap-filling data for synoptic weather forecasting. It is argued that from a joint technology, science, and operational standpoint that a cost-effective realization of the PATH goals, but with the additional features of global coverage and improved NWP sensitivity, can be achieved by a low-cost random-orbit constellation of CubeSats supporting the ATMS and 118 GHz bands. The CU PolarCube mission will be discussed as a basis for this fleet concept.
