Title:
【発明の名称】パルスドップラ信号のフーリエプロセッシング方法および装置
Document Type and Number:
Japanese Patent JP2849827
Kind Code:
B2
Abstract:
A processor for pulsed Doppler velocity measurement utilizes a two-dimensional discrete Fourier transform to map wideband signals into a frequency space where constant velocity Doppler spectral components are represented as radial lines. A radial projection then extracts target velocity information.
