Description
Summary:Precise and accurate position estimation has become crucial to solving many technical problems. This contribution gives an overview of the LPM local positioning measurement system, which is based on the frequency-modulated continuous-wave radar principle. LPM uses two active transponders within each measurement cycle: one acts as a time reference for all base stations, while the other is mounted on the object whose position is to be determined. By evaluating the time-difference of arrival at several base stations surrounding the measurement field, the position can be precisely estimated. We demonstrate this using measurement data.
