A novel approach to the computation of the APES and CAPON spectra for the two-dimensional case is proposed. It is significantly faster than the available methods. An efficient implementation of the PSC estimator is also obtained. The computational technique is mainly based on results for fast computation of convolutions, products of trigonometric polynomials and Cholesky factors. Numerical examples demonstrate the application of APES to synthetic aperture radar imaging.
