WebIncoherence property: We may take the coherence parameter (F)to be the smallest number such that with a=(a[1];:::;a[n])∼F, max 1≤t≤n Sa[t]S2 ≤ (F) (1.5) holds either deterministically or stochastically in the sense discussed below. The smaller (F), i.e. the more incoherent the sensing vectors, the fewer samples we need for accurate WebCoherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference.
