摘要： The solid-state radar device includes: a transmission/reception unit configured to transmitting and receiving radio wave signals comprising a modulated signal and a non-modulated signal, which are pulse signals whose frequencies are different from each other; a frequency filter unit configured respectively to extract the modulated signal and the non-modulated signal from the received radio wave signals based on the frequencies; a pulse compression unit generating a pulse-compressed signal by pulse-compressing the modulated signal; a first echo image generation unit configured to generate a first echo image based on the non-modulated signal and the pulse-compressed signal; a wave analysis unit configured to analyze ocean wave information based on one of the non-modulated signal and the pulse-compressed signal; and a display signal generation unit configured to generate a display signal comprising the first echo image and/or the ocean wave information.

摘要： 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.
