Zusammenfassung:	The purpose is to calculate wave information accurately. A signal processing device 10 is provided, which may include a frequency area spectrum generating module 8, an integrating module 17, and a wave information calculating module 18. The frequency area spectrum generating module 8 may carry out a frequency analysis of the echoes from the waves included in a plurality of analysis areas set within the detection area, respectively, and generate frequency area spectrums for the plurality of analysis areas, respectively. The integrating module 17 may integrate echo intensities indicated by each sampling point that constitutes each of the frequency area spectrums while unifying directions included in coordinates of the frequency area spectrum, and generate an integrated frequency area spectrum. The wave information calculating module 18 may calculate wave information that is information related to the waves included in the analysis areas based on the integrated frequency area spectrum, respectively.
