For the MIMO application, the chirp configuration in Table 2 is used.
With this chirp configuration the MIMO performance specified in Table 1 is achieved. The primary goal was to achieve a maximum distance of about 150 m and maximum velocity of +/- 130km/h. See Programming Chirp Parameters in TI Radar Devices for more details. As mentioned in the previous section, in MIMO mode, 6 antennae are used in azimuth and 3 in elevation. The 3 overlapped azimuth antennae cannot be used in MIMO. So, the total of chirps in a MIMO frame is 9 x "Number of chirps per frame per Tx." The Overlapped antennae are used for Vmax extension in TDM MIMO.
