Title:
レーダ信号処理装置
Document Type and Number:
Japanese Patent JP6789439
Kind Code:
B2
Abstract:
A signal cutting-out unit (31) cuts out a signal reflected from a target by a specific length while the cut-out signals are overlapped by a set length. A power spectrum calculating unit (32) calculates a plurality of power spectra from output signals from the signal cutting-out unit (31). A power spectrum reconstructing unit (33) performs power spectrum reconstruction by changing a ratio or contribution rate of power spectrum components in a set region, using the plurality of power spectra. A spectral moment calculating unit (34) calculates a spectral moment from a power spectrum reconstructed by the power spectrum reconstructing unit (33).
