“…Figure 14 depicts the curves of ξ T versus the phase factor ϕ when the power ratio r and the amplitude factor |ρ| are set at 1 and 0.1, respectively. http://engine.scichina.com/doi/10.1007/s11432-011-4525-z From Figures 9-14 we can summarize the results for both the RARE and the MUSIC algorithm as follows: 1) The resolving threshold decreases as the number of snapshots improves; 2) The resolving threshold improves as the power ratio increases, which conforms to the results in [17]; 3) The resolving threshold improves very fast along with an increasing amplitude factor, but it takes a slow and periodical fluctuation when the phase factor increases, because how the two sources are correlated relies heavily on the amplitude factor; 4) The resolving threshold exhibits the characteristic of a convex function as the power ratio, but takes the property of a concave function as the amplitude factor, i.e., the increasing rate of the resolving threshold decreases as the power ratio increases, but increases as the amplitude factor increases.…”
