AWR1243天线矫正问题

工作人员你好,我们使用AWR1243进行MIMO成像,在使用手册当中有这么一个说法:

对应Signal Processing with 4 Chip Cascade.pdf 4.2节

F = 2pi×ΔP×fs_calib/fs_chirp×f_chirp/f_calib/(N×I_interp)×n

is the FMCW chirp frequency slope used for calibration which can be different from ℎ; is the FMCW chirp sampling rate used for calibration which can be different from the sampling rate ℎ applied in the actual data.

这里的f_chirp和f_calib有什么区别么?fs_chirp和fs_calib同理。这里有点理解不了,向你们求教,谢谢。
