IBSM Equation 3-29. Blur due to constant angular line-of-sight motion during the integration time.

Parameters:

u – angular spatial frequency coordinates (rad^-1)
v – angular spatial frequency coordinates (rad^-1)
a_x – line-of-sight angular drift during one integration time in the x direction respectively (rad)
a_y – line-of-sight angular drift during one integration time in the y direction respectively (rad)

Returns:
