SIGNAL PROCESSING APPARATUS |
摘要 |
A signal processing apparatus includes a 2-dimensional conversion processing section, a 2-dimensional emphasis and attenuation processing section and a 2-dimensional smoothing processing section. The 2-dimensional conversion processing section maps an observation signal in a first coordinate system into a second coordinate system to output a 2-dimensional converted signal. The observation signal includes a detection object component and a noise component to be attenuated, and the noise component is composed of a first noise component and a second noise component. The 2-dimensional emphasis and attenuation processing section attenuates the first noise component to emphasize the detection object component and outputs a 2-dimensional filtered signal in which the detection object component is emphasized. The 2-dimensional smoothing processing section attenuates the second noise component contained in the 2-dimensional filtered signal, and outputs a 2-dimensional smoothing signal, whereby a detection object can be detected based on the 2-dimensional smoothed signal.
