A Novel Method for Target Localization and Doppler Frequency Estimation in Bistatic MIMO Radar
一种新的双基地MIMO雷达目标定位和多普勒频率估计方法

This paper presents a novel method for target localization and Doppler frequency estimation in bistatic MIMO radar. By utilizing the biorthogonality of matrices, a reasonable cost function is constructed. Via iteratively solving the cost function and a systematical multistage decomposition process, the two-dimensional angles and Doppler frequency of each target are estimated in turn. Simulation results demonstrate that compared with the ESPRIT based methods, this new method has the Doppler estimation capability, can eliminate the effect of the transmitted waveforms on target localization and is applicable to sensor arrays without an invariance structure.
