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

估计精度接近CRB界.

Abstract

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.
