A 77-GHz FMCW MIMO Radar Based on an SiGe Single-Chip Transceiver

The Future of Ultra Wideband Systems in Medicine: Orthopedic Surgical Navigation

“…Similar accuracy levels (0.5-20 cm) have been achieved for both carrier-based Waldmann, 2008;McEwan, 2004) and impulse-based (Low, 2005;Zetik, 2004;Ossberger, 2004;Fuiji, 2007) UWB positioning systems, although carrier-based systems have shown the potential for mm and sub-mm range accuracy even for 3-D indoor environments McEwan, 2004). FMCW has proven to be a successful competing technology for high accuracy positioning systems (Stelzer, 1999Mosshammer, 2007;Tragas, 2007;Feger, 2009). In the 5.8 GHz band for industrial, medical, and scientific (ISM) applications, documented accuracy of 5-20 cm for 2-D has been achieved Mosshammer, 2007;Tragas, 2007).…”

“…FMCW systems operating at higher frequencies including 35 GHz and 77 GHz have achieved accuracy levels of 0.1 mm (Stelzer, 1999, Feger, 2009) with the system described by Feger et al working at ranges of up to 10 m (Feger, 2009). The most recent FMCW trend is a European-wide push to create low power wireless sensor networks built on 5.8 GHz FMCW technology Mosshammer, 2007;Tragas, 2007;Feger, 2009). …”

Design and Implementation of a FPGA and DSP Based MIMO Radar Imaging System

“…As a kind of signal form employed in wideband radar, frequency modulated continuous wave (FMCW) signal contributes to a fine capability of ranging and low power consumption [5]. Since the orthogonality between the different transmit signals can be realized through the time division multiple access (TDMA) method [6], switching the array channels to transmit FMCW signal at different time slots became a reliable and popular scheme for MIMO imaging radar [7]- [11].…”

“…Some MIMO radar systems have been developed for radar system performance analysis and algorithm verification [7]- [11], [15]. In [7], a 77-Ghz FMCW MIMO radar is implemented for 2D target localization using an SiGe single-chip transceiver. In [8], a 2D-MUSIC algorithm for joint estimation of angular and range target locations is applied to the MIMO radar system.…”

3-Dimension Burden Surface Imaging System with T-shaped MIMO Radar in the Blast Furnace

“…Compared to the four different radars systems, mentioned above, MIMO radar yields enhance the imaging resolution at significantly reduced cost. [9][10][11][12][13] For this reason the technique is particularly suitable for industrial applications such as BF burden surface detection. However, to date, no one has yet advocated that MIMO radar be used in the BF industry or, for that matter, in any other harsh environment.…”
