I have a doubt on the way the transceiver chips capture data in cascade radar. Which of the 3 ways mentioned below does the radar use to capture data?
1. Each transceiver chip sends a single chirp in a round-robin fashion. Eg Transceiver1(T1) sends the first Chirp(C1) then T2-C1, T3-C1, T4-C1. It goes on till T4(the fourth transceiver) sends out the last chirp.
2. Each transceiver chip transmits a frame sequentially. Eg T1 sends C1, C2...C(last), then T2 sends C1...Clast and so on.
3. Each transceiver chip captures all of its frames before the next one starts capturing.
If the actual case is different than these three, please let me know. Also If you could point me to the location of the literature detailing this capture process, that would be great.
The data transmission is sumilar to the case when there is a single sensor.
Are you clear about how transmission works with single sensor, i. e. notion of chirp and frame?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Cesar:
If I understand correctly, a single sensor system sends all the chirps sequentially till the required number of frames are captured. So would that mean the sensors in cascade capturing frames in parallel, correct? Can I think of it as 4 independent single-sensor systems?
In reply to Asher Farooqui:
You can think of it as a single sensor that has 12TX and 16RX antennae. On the antenna we provide some antennae are overlapped.
Thank you for the response. Could you point me to the documentation detailing the capture process? I'm having a little trouble understanding how it implements MIMO if I think of it as a single sensor with 16Rx and 12 Tx.
The matlab scripts provided should provide some help.
Conceptually there is no difference between 3Tx/4Rx and 12TX/16Rx
