The matched filter

The matched filter is the optimal linear filter for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise. Matched filters are commonly used in radar, in which a known signal is sent out, and the reflected signal is examined for common elements of the out-going signal. Prikaži več In signal processing, a matched filter is obtained by correlating a known delayed signal, or template, with an unknown signal to detect the presence of the template in the unknown signal. This is equivalent to Prikaži več Derivation via matrix algebra The following section derives the matched filter for a discrete-time system. The derivation for a continuous-time system is similar, with … Prikaži več When viewed in the frequency domain, it is evident that the matched filter applies the greatest weighting to spectral components exhibiting the greatest signal-to-noise ratio (i.e., … Prikaži več • Periodogram • Filtered backprojection (Radon transform) • Digital filter Prikaži več Derivation Matched filtering can also be interpreted as a least-squares estimator for the optimal location and scaling of a given model or template. Once again, let the observed sequence be defined as Prikaži več Radar and sonar Matched filters are often used in signal detection. As an example, suppose that we wish to judge … Prikaži več • Turin, G. L. (1960). "An introduction to matched filters".

Despite this diversity of purpose, all matched filter applications operate in essentially the same way. SpletA matched filter is often used at the receiver front end to enhance the SNR. From the discrete signal point of view, matched filter coefficients are simply given by the complex conjugated reversed signal samples.
