“…The radar units continuously measured their distance and receiving angle. All measurements where reference to a pair of optical tachymeters which were also used to track the movements of the boom [11]. The standard deviations of the errors of the distance and angle measurements with respect to the results of the optical tachymeters are only 2.66cm and 0.16 • , respectively.…”

“…Due to the difference in distance ∆D i the IF signals observed in each receiving path show a corresponding phase shift ∆ϕ i . Since the spacing ∆A i of the antenna elements is known the AOA of the radar signals can be calculated by applying the classical beamformer [11]. Distance and velocity measurements are performed as described in section II-B.…”

We extend the conventional FMCW radar concept for primary radar systems to secondary radar systems. In the first setup we show how two radar devices are synchronized to each other in order to measure their 1D-distance to each other. We then present two methods to extend the system to multiple units thereby enabling the estimation of a 2D-position. Finally, we present a novel system configuration incorporating multiple receiving antennas to measure both the 1D-distance between the radar units and the angle of arrival of the radar signals. By measuring the distance and the angle of arrival the number of radar units required for 2D-positioning can be reduced significantly, thus enabling new applications.
