 (ā′lē-ə-sĭng, āl′yə-)
1. Visible or audible distortion introduced into digital information, such as images or audio signals, caused when a continuous line or transition is not smoothly captured or represented because of the low resolution or sampling rate of a digital medium.
2. The appearance of jagged distortions in curves and diagonal lines in computer graphics.

Unfortunately, the problem of spatial aliasing from the grid that has plagued the Eulerian 3D fluid-body interaction methods is also present in our method.
While it is possible to acquire a dense, high-resolution grid of 2D lines or create a mesh of 2D coverage by assembling spatially coincident 2D surveys of different vintages [3], unless the data are sampled in 3D, spatial aliasing is difficult to circumvent 4].
Spatial aliasing occurring in microphone arrays--due to the discrete sampling in space--makes it very challenging to accurately estimate the DOAs across the whole spectrum of frequencies.
lobes not associated with a source but as a result of spatial aliasing effects due the discrete nature of the array.
