  This paper focuses on the problem of localising a transmitting mobile station
(MS) using multiple cooperative base stations (BSs). There are two technical
difficulties: one is the data association between intermediate parameters and
scatters; the other is to identify Line-of-Sight (LoS) and Non-Line-of-Sight
(NLoS) paths. Our main contribution is a unified approach bypassing both data
association and LoS/NLoS path identification. This is achieved by introducing
virtual scatters and then a direct localisation formulation. Modern
super-resolution technique is then adapted to cast the localisation problem as
convex programming and solve it. Our approach addresses long-standing issues
not completely solved in the literature, guarantees a global convergence,
achieves good localisation accuracy and demonstrates its robustness to noise in
our numerical tests.
