Abstract:
We introduce a radar system capable of tracking a 5 mm spherical target continuously in three dimensions.
The 10 GHz (X-band) radar system has a transmission power of 1 W and operates in the near
field of the horn antennae. By comparing the phase shift of the electromagnetic wave traveling through
the free space with an IQ-mixer, we obtain the relative movement of the target with respect to the
antennae. From the azimuth and inclination angles of the receiving antennae obtained in the calibration,
we reconstruct the target trajectory in a three-dimensional Cartesian system. Finally, we test the
tracking algorithm with target moving in circular as well as in pendulum motions and discuss the
capability of the radar system.
