Industrial automation requires highly precise distance measurement sensors. Accurate detection of the piston position is indispensable for the control and monitoring of hydraulic cylinder applications. Known external and integrated solutions are subject to many limitations as for example in accuracy, in measurement length, or in price. A promising approach consists in the use of precise and low-cost...
The FMCW radar technology offers the possibility to achieve very high target accuracy mainly limited by the SNR. In this paper the CRLB for an FMCW radar with phase evaluation is derived and different algorithms reaching the CRLB are presented. The algorithms are tested in a simulation and the simulation results are compared with measurement results of an existing FMCW radar. The used algorithms are...
Highly precise distance measurement sensors are essential in the field of industrial automation. In particular hydraulic cylinder applications require an accurate detection of the piston position by reason of controlling and monitoring. Currently used external as well as integrated solutions are limited by many factors. Using low-cost and precise radar sensors is a highly promising approach for these...
