A Micro-Doppler Feature Analysis and Error Factor Compensation in Bistatic FMCW Wideband Radar
摘要
Abstract
The micro-Doppler effect of rotating target is studied in bistatic frequency modulation continuous wave (FMCW)wideband radar in this paper.Firstly,the model of rotating target is established in bistatic FMCW wideband radar,and the expression of micro-Doppler effect is derived.Then,the conclusion is de-duced from the previous that the primary error term causes one-dimensional range profile walk and peak deviation,and the quadratic error term causes the one-dimensional range profile widening,also the maxi-mum of frequency deviation in micro-Doppler feature curve is modulated by the bistatic angle according to the analysis of the influence caused by micro-motion during the pulse repetition interval (PRI)on one-di-mensional range profile .Finally,the error factor compensation approach based on minimum entropy prin-ciple is proposed.The simulation analysis indicates that the use of the method can estimate the coefficient of the quadratic error term in precision and can compensate the error factor of the micro-Doppler effect ef-fectively and is good in anti-noise performance.关键词
