中文摘要:
      针对直升机半物理仿真测量数据主要是低频噪声的特点,提出利用小波变换、塔式结构重构算法,对信号进行降噪滤波处理的方法.仿真结果表明该方法在离线降噪滤波处理上实用高效.
英文摘要:
Pointing to the data obtained from semi physical simulation of certain helicopter which mainly has low-frequency noise, a data processing method of depressing and filtering noise from the signal, using the pagoda-structure re constructing arithmetic and the wavelet transform principle, is proposed. The result of simulation shows that the method is practical and efficient on off-line dataprocessing.
