摘要
为实现线性调频信号参数的快速、准确估计 ,本文通过分段解线调和直接解线调建立了频域波束空间方程 ,并利用Beamspace ESPRIT获得了调频斜率和初始频率的估计 .仿真实验显示算法计算量较小 ,性能优良 。
To realize a fast and accurate parameter estimation of LFM signals,the paper constructs beamspace equations in frequency domain by subsection dechirp and direct dechirp.Then Beamspace-ESPRIT is used to estimate the chirp rate and initial frequency.Simulation shows the proposed method has a low computational cost and high performance close to CRB.
