Near Field Targets Localization Using Bistatic MIMO System with Symmetric Arrays
Résumé
In this paper, we propose a subspace based method
to localize multiple targets in the near field region of a bistatic
MIMO system with symmetric uniform linear arrays (ULAs).
The proposed method uses the symmetry in the transmitting
and receiving arrays to estimate the angle of departure (AOD)
and angle of arrival (AOA) of each target by using 1D rank
reduction estimator (RARE) based method. For each estimated
AOA, the range from the center of the transmitting array to the
corresponding target is estimated by using 1D multiple signal
classification (MUSIC). Finally, the receiver side range of each
target is estimated by using the other three estimated location
parameters in 2D MUSIC technique which also automatically
pairs the location parameters.
