Definition of apodization
electrical engineering
: the process of altering a signal (such as one emitted by an electrical sensor) to make its mathematical description smoother and more easily manipulatable
The system also implements a standard suite of spectral estimation algorithms. The user can … use apodization with different weighting functions or compensate for distortions arising from equal data spacing. — Physics Today, March 1993

Amplitude and phase errors tend to increase at high spatial frequencies, so we weighted the data with a function that is 1 at a frequency of 0 and falls to 0 at a spatial frequency of 2.8 cycles per arc second. A similar function was used to apodize the visibilities before reconstructing the images.
