| 摘 要： | 论述了小波变换在相对运动的接收机问信号参数的估计和提取中的应用，研究了线性运动时延的无限和有源估计的小波算法，起到了噪音过滤作用，提高了时延和多普勒估计的精确性。此外，利用小波变换处理了旋转体回波信号，仿真结果表明，采用波变换后，信号的参数估计的可靠性明显提高，通过选择比例范围，能够获得比常规方法更高的分辩率。

| Abstract: | The paper presents the application of the wavelet transform in the relative motion receiver. The wavelet algorithms in the passive and active estimation, are proposed to reduce the noise and improve estimation accuracy of the delay and doppler.The use of the wavelet transform for processing the echo signal is also discussed. The result of simulation indicates that reliability is increased. Depending on the choice of scales, it can have increased resolutions than the conventional methods. |
