pybsm.otf.functional.tdi_OTF(*, u_or_v: ndarray, w: float, n_tdi: float, phases_n: int, beta: float, f: float) → ndarray

IBSM Equation 3-38. Blur due to a mismatch between the time-delay-integration clocking rate and image motion.

Parameters:

  • u – angular spatial frequency coordinates (rad^-1)

  • v – angular spatial frequency coordinates (rad^-1)

  • w – detector size (width) in the TDI direction (m)

  • n_tdi – number of TDI stages (unitless)

  • phases_n – number of clock phases per transfer (unitless)

  • beta – ratio of TDI clocking rate to image motion rate (unitless)

  • f – focal length (m)

Returns:
