Abstract
We present a test for the detection of nonstationary spatial processes using spectral methods. The spatial field is represented locally as a stationary isotropic random field, but only the parameters of the stationary random field that describe the behaviour of the process at high frequencies are allowed to vary across in space, reflecting the lack of stationarity of the process.
