Description: 指滤波器的性能与信号的特性取得某种一致,使滤波器输出端的信号瞬时功率与噪声平均功率的比值最大.即当信号与噪声同时进入滤波器时,它使信号成分在某一瞬间出现尖峰值,而噪声成分受到抑制。-In signal processing, a matched filter (originally known as a North filter[1]) is obtained by correlating a known signal, or template, with an unknown signal to detect the presence of the template in the unknown signal. This is equivalent to convolving the unknown signal with a conjugated time-reversed version of the template. 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. Pulse compression is an example of matched filtering. It is so called because impulse response is matched to input pulse signals. Two-dimensional matched filters are commonly used in image processing, e.g., to improve SNR for X-ray. Platform: |
