Title:
信号処理装置、レーダ装置、レーダ運用方法およびレーダ運用プログラム
Document Type and Number:
Japanese Patent JP7205014
Kind Code:
B2
Abstract:
A waveform shaping unit (220) accumulates beat signals S9, which are beat signals S8 in frame units. A distance calculation unit (252) generates a histogram of range bins using the beat signals S9, and calculates a distance based on a range bin number corresponding to a peak in the histogram as a relative distance of a target object. A velocity calculation unit (253) generates a power spectrum of Doppler bins for each time period or for each range bin using the beat signals S9, generates a difference statistic graph that indicates a statistic of differences between power spectra, and calculates a velocity based on a Doppler bin number corresponding to a peak in the difference statistic graph as a relative velocity of the target object.
