(color online) Numerical experimental demonstration of SISC-SSI for a gray-scale object. (a) Original object. (b₁)–(b₅) The results of SISC-SSI in the detection SNR = ∞, 20 dB, 15 dB, 10 dB, and 5 dB, respectively, and the speckle’s number is 5. (c₁)–(c₅) The results of SISC-SSI when the speckle’s number is 1, 5, 10, 15, and 30, respectively, and the detection SNR is 10 dB.
