Claim 8:
9. The spectral restoring method according to claim 8,
wherein obtaining the restoring tensor based on the first constraint equation and the second constraint equation comprises obtaining the restoring tensor based on the first constraint equation, the second constraint equation and a third constraint equation, and
wherein the obtaining the restoring tensor based on the first constraint equation, the second constraint equation and the third constraint equation comprises:
multiplying the first constraint equation by a sensitivity coefficient, and adding the product to the second constraint equation and the third constraint equation to obtain a combination equation, represented as:

g(ck)=∥ckÂ∥22+λ∥(Dck)∥22+α(ckÂsk−1)2→0;

deriving and zeroing the combination equation, represented as:

g′(ck)=0;

obtaining the channel restoring vector as:

ck=α(ÂTÂ+λDTD+αskTÂTÂsk)−1·Âsk.
