Tool/software:
My application requires target tracking and velocity measurements of small targets up to 320 kmph. I see that the native maximum velocity obtained using a two-dimensional FFT on the frame data is 133 kmph.
1. Can adjustments be made in a custom design to increase this maximum velocity to 320 kmph, or is this a hardware limitation?
I've seen for other TI radar sensors that the range and azimuth angle is still accurate even if the velocity exceeds the maximum velocity.
2. Will the range and azimuth angle be accurate for targets traveling faster than the maximum velocity?
My application requires long range and both azimuth and elevation angle readings. It would be acceptable to use a beam with narrow elevation angle and scan it through the elevation angle range.
3. Is it possible to use the AWR2243 to use TX beamforming to scan the elevation angle? If so, is it possible on the cascade EVM board?
For my application, I only need to track the elevation angle for the first portion of the targets flight path. Once the ballistic trajectory has been determined, It would be preferable to use TXBF to track the target for as far as possible as it moves away from the antenna.
4. How quickly can the AWR2243 be reconfigured from MIMO to TXBF? Is this a practical use case for the chip? Can it be done with the cascade EVM board?
