Multi-target super-resolution using compressive sensing arguments for multipath interference recovery

The multipath interference (MPI) adds noises to the time-of-flight (TOF) measurements and then causes depth estimation inaccuracy. This paper combines multi-frequency TOF (MFT) acquisition and compressive sensing (CS) approaches to reconstruct the multipath reflections. Mismatch model and depth resolution problems will be analyzed to achieve a good measurement accuracy with a high probability.
