In strong noisy jamming environment, it is possible for 2~ 3 neighbor jammed radars to change its work mode from active detection to passive detection, and to locate noisy source in the air. 在强噪声干扰环境中,将邻近2~3部受干扰的陆基雷达,从主动探测转入被动探测工作,利用干扰信号对空中干扰平台进行无源定位是可能的。
A method to process noisy pressure signals with EMD ( empirical mode decomposition) algorithm is studied in order to ensure validity of collected pressure signal samples. 研究了运用EMD算法(Empiricalmodedecomposition,经验模态分解法)对含噪压力信号进行处理以提高压力信号采样有效性的方法。
As a safe and comfortable, green, less noisy and pollutive traffic mode, magnetic levita-tion vehicles has become the important modern symbol of the human ground passenger transport. 具备安全舒适、绿色环保、噪声和污染小等性能的磁浮列车,是人类地面客运交通运输现代化的重要标志。
