In this paper, we present a radar sensor system for real-time blast furnace burden surface imaging inside a fully operative blast furnace, called BLASTDAR, the blast furnace radar. The designed frequency-modulated continuous-wave (FMCW) radar sensor array operates in the frequency band around 77 GHz and consists of several nonuniformly spaced receive and transmit antennas, making it a multiple-input multiple-output radar system with large aperture. Mechanical steering is replaced by digital array processing techniques. Off-the-shelf automotive-qualified multichannel monolithic microwave integrated circuits are used. By means of this configuration, a virtual antenna array with 256 elements was developed that guarantees the desired angular resolution of better than 3°, and a range resolution of about 15 cm. Based on the single-channel FMCW signal model, this paper will derive a multichannel signal model in combination with a digital beamforming approach and further advanced signal processing algorithms. The implementation of a simulation tool covering the whole design process is shown. Based on these simulation results, a system configuration is chosen and the obtained setup is defined and presented. A description of the manufactured cost-efficient radio frequency and baseband boards together with the housing design shows the practical implementation of the sensor. For the system calibration, two different methods are listed and compared regarding their performance. Verification measurements confirm the predicted performance of the developed sensor. Several measurements inside a fully operational blast furnace demonstrate the proper long-term functionality of the system, to the best of our knowledge, for the first time worldwide. It is in continuous operation since about two years in blast furnace #5 of voestalpine Stahl GmbH, Linz. © 2015 IEEE.

We present the realization of a cooperative radar system for ranging applications with integrated data-transmission capability. The simultaneous transmission is performed by the radar-hardware without the necessity of additional components or an auxiliary data-link. Therefore, the data are directly embedded in the transmitted chirp of a frequency-modulated continuous-wave radar sensor. A second station, acting as receiver, uses an identical, but unmodulated chirp for down-conversion. The resulting signal then is processed by a non-coherent demodulator setup, extracting the communication data. Measurement results from transmission of messages with different bit-rates are shown. By utilizing existing radar-hardware a transmission rate of up to 256 kbps is possible, without the need of a dedicated transceiver. Additionally, a method to optimize the ranging results by variable distribution of the available signal power between distance-measurement and communication system is presented.

We present the implementation of a cooperative radar system on a gantry rail crane for distance measurements in an industrial environment. The measurement approach is based on the dual-ramp frequency-modulated continuous-wave principle, using identical sensor-nodes at the endpoints of the range of interest. Pseudo-range information is exchanged via a dedicated data-link between these stations. At the sensor-node a flexible high-performance signal processing and remote management engine is implemented. The system setup is controlled by a single host-PC, which is used as a man-machine interface for configuration of the remotely controlled measurement stations, system surveillance, and visualization of the measurement data. Indoor characterization of the developed hardware is sufficient for an efficient calibration of the system, minimizing distance offsets. On-site measurements at distances up to 1000 m with an accuracy better than 2 cm confirm the performance of the ranging system. Furthermore, the results are verified by simulation.

In addition to the initial cost of wind turbines, availability and effectiveness of the technical equipment are key factors for a profitable economical operation. In this context suitable software tools become essential for an efficient operation and maintenance of wind farms. HAICMON widens the borders of a classical condition monitoring system based on vibration measurement and integrates relevant process data from different sources. The highly flexible hard- and software architecture allows the acquisition of data from particle counters, converters, power station and so on. Figure 1 shows a typical system architure. All data is stored within a central data warehouse based on a high performance database system. HAICMON makes correlation analysis in order to consider relevant relations between single data points to recalculate significant indicators. In case of vibration analysis it is inevitable to combine the measured vibration levels with process conditions like the load, rotation speed, oil temperature and so on for getting meaningful trends. Also the experience of the windfarm operators and maintenance crew are valuable sources for additional information. These sources need to be integrated into the system in an easy way. HAICMON takes this into account by providing so called "virtual trends". In addition to maintenance purposes HAICMON supports the technical operators with extensive analysis and reporting functions for availability, fault analysis, output, wind distribution and many more.

An apparatus is described for measuring the deposition of ice on the rotor blades (5) of a wind turbine (1), having a transmitting and receiving device with parts that are on the rotor blades (5) on the one hand and parts that are arranged in fixed positions and are connected to each other via a wireless transmission link on the other and having an evaluation circuit (9) connected to the transmitting and receiving device. In order to provide advantageous structural conditions, it is proposed that the transmitting and receiving device comprises passive transponders (6) on the rotor blades (5) and at least one stationary reader unit (7) for the transponders (6) and the evaluation circuit (9) has a comparator stage (10) for the minimum transmission output of the reader unit (7) required to read the transponders (6) reliably, with a programmable threshold value for this transmission output in the event of the deposition of ice.
