基于OFD-LFM信号的MIMO雷达微多普勒效应分析
MIMO Radar Micro-Doppler Effect Analysis Based on OFD-LFM Signal
摘要
Abstract
Compared with traditional monostatic radar system, multiple input multiple output ( MIMO) radar system can receive returned signals from targets in different aspects wich respect to the transmitting/receiving radar pairs by utilizing the spatial diversity technology and can ohtain more target information, which highly improves the radars estimation accuracy of target moving parameters. Based on the MIMO radar system with orthogonal frequency division linear frequency modulation ( OFD-LFM) signals,the micro-Doppler effect caused by rotating parts of the target is deduced in detail and then the rotation radius is estimated by calculating the mathematical expectation of the obtained data. Simulations are given to validate the theoretic conclusions and prove that the estimated rotation radius obtained in is very close to its real value.关键词
