Multi-target Localization with MIMO Radar via Coupled Canonical Polyadic Decomposition

In this paper, we innovatively introduce coupled canonical polyadic decomposition (C-CPD) into a Multi-Static-Multi-Pulse MIMO radar system, which consists of one transmit subarrays and multiple spatially-distributed receive subarrays, to localize targets. In the system, the received signals at each receive array can be stacked into a third-order tensor that admits CPD, and these tensors together follow C-CPD. Therefore C-CPD based algorithms can be applied to these stacked tensors to calculate the related factor matrices, some of which can be used to extract the position information of the targets, as presented in this paper. It is worth noting that our used method does not require the probing signals are mutually orthogonal. Nor do their waveforms need to be known. Experimental results shown in the last section will validate all of our claims.
