摘　　要：由于超低空导弹工作在海杂波背景下,其引信的信号检测易受干扰。传统的信号处理方法效果不佳,而小波变换有多分辨分析的特性,可以有效滤除杂波带来的噪声,然后根据回波信号频率,辨别真假目标。基于雷达引信实测数据进行仿真,实验结果表明,该方法能够有效滤除大部分噪声信号,从而提高超低空导弹作战能力。Due to the extra-low-altitude missile working on the background of sea clutter, its fuse will be jammed easily. And the traditional signal processing methods behave badly,however wavelet transform has the multi-resolution rate characteristic. It can filter noises in the clutter signal and improve the precision of the fuse machine, so the real object will be identified according to the size of the echo frequency. The simulation is based on the testing data of radar fuses,and it indicates that this algorithm can effectively filter most of the signal so that it can promote the fighting efficiency.
