%X The property that the ordered statistics CFAR(OS-CFAR) detector can obtain constant false alarm rate under homogeneous Log-normal distributed clutter background is proved in this paper, when the shape parameter of probability density function is known. Both the detection performance expressions with non-fluctuating target and the ADT (average decision threshold) expressions of the OS-CFAR detector are derived. Finally, the optimal order value and the signal-clutter-ratio losses compared with ideal CFAR of the OS-CFAR detector are discussed by numerical method when the number of reference cells is taken different values.
