(color online) The SNR simulation result as a function of radius r and baseline b. Here, R and B are dimensionless quantities divided by constant D = 15 mm for uniformity consideration. The curve projected on the XZ plane represents the relationship between SNR and R when B is set to 5. And the curve on the YZ plane shows how B affects the SNR when R = 1.
