The effects of detectornoise on imaging are simulated with the three-dimension model.
利用三维噪声模型，模拟了探测器噪声对图像质量的影响；

As for detectornoise, we simulate it as Gaussian Whitenoise, referring to the instrument parameters of 21CMA and LOFAR.
对于仪器噪声，我们用高斯白噪声进行模拟，并参考了21CMA和LOFAR的仪器参数。

In this system the detected signal difference between two neighbouring instantaneous times is served as the effective signal, and the system noise points at the detectornoise.
