摘要
A signal processing device for processing a signal of a reflected wave which is a wave reflected in a medium and is received by a receiver, when a wave propagating through the medium is continuously transmitted by a transmitter. The signal processing device includes: an estimation unit configured to estimate a lower limit distance of a detection distance range for which an intensity level of a scattered wave from the medium in the detection distance range is equal to or smaller than an allowable level; and a scattering reduction unit configured to remove, from a signal of the reflected wave received, a signal of the scattered wave from the medium in a masking region from the receiver to the lower limit distance to perform output.
