AI Technical Summary
Existing target localization methods in non-line-of-sight scenarios rely on accurate prior knowledge of building layout. When scene information is unknown, localization performance degrades, and accurate localization is difficult to achieve in multi-target environments.
By constructing a multipath echo signal model, analyzing the relationship between the departure and arrival directions of multiple paths, designing a multipath identification strategy, and combining multipath arrival time information, the joint estimation of non-line-of-sight building layout and target location is achieved.
It achieves accurate estimation of building layout and target location in non-line-of-sight multi-target environments and has high-precision path recognition capabilities.
