摘要
A signal processing device (40) is provided. The device includes an echo signal input unit (30) for receiving echo signals resulted from transmission signals reflected on an object. The transmission signals are transmitted from a transmission source (20) at transmission timings at predetermined time intervals, at least one of the transmission timings shifted from the other timings in time. The device includes a complex reception signal generator (42) for generating complex reception signals, a phase calculator (43) for calculating a phase change amount of the complex reception signals with respect to a reference phase, a phase corrector (44) for phase-correcting the complex reception signals and outputting the corrected signals, and a Doppler processor (45) for performing Doppler processing on the corrected signals and outputting the Doppler-processed signals as Doppler echo signals of the object.
