摘要
分析了基于宽带信号的时延和多普勒联合估计方法,应用广义相关理论,提出一种基于广义相关的时延和多普勒联合估计算法,并通过仿真证明了这种方法的有效性。
In this paper we discuss the application of the wavelet transform in the joint time delay and Doppler stretch estimation for a wide band signal and put forward a special generalized correlation algorithm for estimation of time delay and Doppler. This algorithm is more efficient and suitable for more generalized signal and noise conditions by the simulations.
