I use Cascade_ Configuration_ MIMO. Lua configures radar parameters and uses the provided MATLAB program cascade_ MIMO_ SignalProcessing performs signal processing. The adcData of each frame can be obtained through the program. Its dimension is (256 * 64 * 16 * 12). 16 represents the index of the receiving antenna and 12 represents the index of the transmitting antenna. From the code, I can know that the index of the receiving antenna corresponds to the Rx Antenna in the following figure, but how does the index of the transmitting antenna correspond to the Tx Antenna in the following figure?
Perhaps the following pictures can provide more information about the transmitting antenna.
