Low angle estimation in MIMO radar based on unitary ESPRIT under spatial smoothing
IET Radar, Sonar &Navigation, Volume 18, Issue 10, Page 1829-1836, October 2024.A low elevation estimation algorithm based on unitary ESPRIT is proposed for the multi‐input and multi‐output (MIMO) radar. Firstly, the virtual matrix vectorisation is processed by generalised matching filtering of MIMO radar multipath signals. To solve the problem that the unitary ESPRIT cannot handle directly after vectorisation of the virtual ...
