2.3.1.2 Antenna Configuration

The TIDEP-01024 uses four receivers and three transmit antennas, as shown in Figure 2-3. When the system operates in time-division multiplexed (TDM) MIMO mode, a nonuniform, synthesized array of twelve antennae is achieved, as shown in Figure 2-3. The TDM mode of operation is achieved by transmitting chirps using TX1, TX2 and TX3 in an alternate fashion. This antenna fashion has been designed for directional of arrival (DOA) detection in both azimuth and elevation.
