Hi,TI team!
The structure of 12 transmitters and 16 receivers of the MIMO mode subordinate radar means that its antenna aperture D=85 * lambda/2=165mm. According to the far-field determination formula, Rff=2 * D ^ 2/lambda=13m. Soit is finally calculated that the far-field is about 13m away, that is, it is considered to be a far-field beyond 14m. But why the mmwave_ studio_ cascade_ user_ guide.pdf emphasize the calibration should be carried out beyond 5m, but 5m should be in the near field theoretically. I don't understand the theoretical basis for this?
In addition, if the MIMO mode of cascaded radar is used for measurement in the near field, such as at a distance of 1 m to 5 m, should near-field angle estimation and near-field correction be used? Is there any reference for TI?
Look forward to your reply, thank you!
