The fast Fourier sampling (FFS) method is related to the new sampling paradigm, compressive sampling (CS). This paper explores the application of the FFS method in an ultra-wide band digital receiver. The aim of the study is to quickly detect sparsely distributed carrier frequencies in an ultra-wide frequency band using fewer digital sampled data when compared to ubiquitous methods, such as the fast Fourier transform (FFT). Study shows that the FFS method can be applied to ultra-wide band sparse radar signal detection using randomly selected data from conventional analog-todigital converter and has the added advantage that it can be implemented on DSP hardware using a short-length of FFT.
