I appreciate your great work. In pc_generate.py, you are trying perform FFT along 4 virtual antennas. elevation_ant = virtual_ant[2 * num_rx:, :] However, from the TI website (https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1018413/iwr1843boost-range-elevation-heatmap-processing), they suggest perform FFT along two separate rows of virtual antennas. Does your method follow the same strategy provided by TI?

In the code as you mentioned, num_rx is 4. So the FFT is performed on 8 virtual antennas.

感觉应该是2跟虚拟天线，四根是错误的吧。俯仰角有四对，但是只有一对（两根）可以测俯仰角，后面直接连续的四根天线FFT只能测方位角，俯仰角要选天线对，两两成对。

Yes, I am Confused.

这是方位角8根，提问的应该说的是俯仰角
