提出了一种基于非线性双稳随机共振系统的毫米波辐射计输出信号去噪方法。文章首先介绍了非线性双稳随机共振系统用于强噪声背景下去噪的原理,使用频率压缩技术将毫米波辐射计输出信号频率降低。使用该方法在提高辐射计输出信号的信噪比上有明显优势。
A method based on nonlinear bistable stochastic resonance system is proposed for the output signal denoising of millimeter radiometer. The paper first introduces the principle of nonlinear bistable stochastic resonance system for denoising in the background of strong noise, and uses the frequency compression technique to reduce the frequency of the millimeter radiometer output signal. Using this method has obvious advantages in improving the signal-to-noise ratio of the radiometer output signal.
