Title:
信号処理装置、レーダ装置、およびレーダ装置の設定方法
Document Type and Number:
Japanese Patent JP6659400
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a signal processor which can suppress variations in signals between antenna elements, a radar system, and a method for setting the radar system.SOLUTION: A signal processor according to an embodiment includes a setting part, a correction part, and a processing part. The setting part sets a coefficient used for correcting the amplitude and the phase of a reception signal supplied from each of antenna parts arranged in a first direction, on an antenna-part-by-antenna-part basis. The correction part corrects a reception signal supplied from an antenna part based on the coefficient for an antenna part set by the setting part. The processing part generates reception data based on a plurality of reception signals corrected by the correction part. The setting part generates one-dimensional data including the respective amplitudes and the phases of the antenna parts based on the reception data generated by the processing part, and sets a coefficient for each antenna part based on results of comparison between the one-dimensional data and reference data.SELECTED DRAWING: Figure 1
