Patent ID: 8184268

Claim:
A method for multi-target-enabled resolution of phase ambiguities, comprising: emitting a periodic signal to at least two objects present within an ambiguity interval, the signal having at least J≧2 wavelengths λ j with 1≦j≦J; receiving the signal reflected by the objects; deriving the phases φ j as a phase shift for each of the wavelengths λ j from the received signal and decomposition into single-object phases φ ij with 1≦i≦I assigned to the I≦2 objects; dividing the ambiguity interval into cells of defined width, a counter reading and a distance being assigned to each cell and a counter reading distribution being derivable; incrementing the counter reading for the cells which are assigned to the possible object distance R N (φ ij )=φ ij /2π·λ j /2+N·λ j /2, the incrementation being effected for NεN which can be assigned to the ambiguity interval as a periodicity control variable for all NεN which can be assigned to the ambiguity interval and for all single-object phases φ ij ; and determining an absolute object phase and/or a true object distance for at least one of the objects.
