Abstract
A joint 4-dimensional (4-D) angle and Doppler shift estimation method is proposed for bistatic multiple-input multiple-output (MIMO) uniform rectangular array (URA). The key idea behind the proposed approach is to use tensor decomposition to estimate the target parameter matrices, and use Vandermonde structure enforcing strategy to regress the parameters. This algorithm can effectively estimate all the parameters simultaneously, and requires neither parameter pairing nor multi-dimensional nonlinear peak searching.
