1. A method of a computer system comprising: determining, based at least in part on one or more characteristics relating to a physical measurement system that acquires survey data regarding a target structure, a polygonal space in a Fourier domain; computing a representation of a function that is bandlimited within the polygonal space, the function producing a valid output in a frequency range and a wavenumber range of the polygonal space; and performing a computation on measurement data collected by the physical measurement system, the computation using the representation of the function.
