Matched Filter part of Radar Signals Wiley-IEEE Press books

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. Pulse compression is an example of matched filtering. It is so called because the impulse response is matched to input pulse signals. Zobacz więcej 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 Zobacz więcej Derivation via matrix algebra The following section derives the matched filter for a discrete-time system. The derivation for a Zobacz więcej When viewed in the frequency domain, it is evident that the matched filter applies the greatest weighting to spectral components … Zobacz więcej • Periodogram • Filtered backprojection (Radon transform) • Digital filter • Statistical signal processing Zobacz więcej Derivation Matched filtering can also be interpreted as a least-squares estimator for the optimal location and scaling of a given model or template.
