Imaging Method Based on Time Reversal Channel Compensation: Scientific Approach

The conventional time reversal imaging (TRI) method builds imaging function by using the maximal valueofsignalamplitude. Inthiscircumstance,someremotetargetsaremissed(near-farproblem)or low resolution is obtained in lossy and/or dispersive media, and too many transceivers are employed tolocatetargets,whichincreasesthecomplexityandcostofsystem. Tosolvetheseproblems,anovel TRI algorithm is presented in this chapter. In order to achieve a high resolution, the signal amplitude corresponding to focal time observed…
