TIDEP-01012: Repetitions in the Amplitude image

Part Number: TIDEP-01012

Dear TI-team,

I acquired some dataset with our TIDEP-01012 in the MIMO and TXBF-mode. In MIMO everything works out fine. However, when I use the TXBF-mode a repeating pattern (highlighted in yellow) occurs on the right side of the stich range/azimuth image:

We can not understand why this happens as it is also not constantly showing up and does not always have the same angular extension.

- It seems not to show up when the angles are set to the original values of 30:2:30.

- It shows up when changing the angles to 75:2:75 or also 70:1:70.

- It sometimes shows up when the angles are set to 30:1:30 (example above) but sometimes the measurement is fine (example below). Both example occured in the same acquisition where we acquired 10 frames.

What could be the reason and how to avoid it?

Thanks for your help,

Andreas
