SAR Radar feasability check

Our goal is, to build a SAR (Synthetic Aperture Radar) with the AD9361.
We are going to send on 2 Antennas an identical signal for a short time.
So the 1R1T mode of the AD9361 couuld be used. After the sent pulse, we are going to listen with 2 separated antennas. So the 2R mode is required.
The listening BW shall be as high as possible. (56MHz)
So the AD9361 continuously operates:
1T1R
2R
1T1R
2R
.
.
The main question is:
- What time it takes to switch between those 2 modes?
- Is the BW of 56MHz a valid BW, or are there other limitations preventing that the FPGA sees that BW?

 

Many thanks
