Title :
On Understanding the Matched Filter in the Frequency Domain

Abstract :
A matched filter is viewed as a cascade of a spectral-phase matched filter and a spectral-amplitude shading filter. The former provides the peak output in time, and the latter guarantees that that peak has maximum signal-to-noise ratio (SNR), or the latter may alternatively be chosen to provide better time resolution.
