双谱时延估计在被动测距中的应用
Application of Bispectrum Time-delay Estimation in Passive Ranging
摘要
Abstract
Time delay estimation is the key for the passive ranging sonar to achieve accurate positioning. The paper mainly researches the application of bi-spectrum time-delay estimation to passive ranging on the basis of introducing correlated time-delay estimation. According to the theoretical analysis and simulation results, bi-spectrum time-delay estimation has many advantages compared to the correlated time-delay estimation, such as accurate time-delay estimation, smaller error and better capability to remove Gaussian noise.关键词
