In this paper, we formulate the signal-to-noise ratio (SNR) of a direct-detection imaging system in turbulent media. From the formulation, we find that the SNR varies in the image plane and that the object radiation pattern affects SNR dramatically. An example is given to demonstrate the turbulence effect on the degradation of SNR. For simplicity, an object with a gaussian pattern, like that of a multimode laser, is used in the example.
