Optimum passive bearing estimation
Webadshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A Websignal has been detected, an important passive sonar problem is to estimate the time delay D between two sensors separated by length L. This time delay estimate then is used to estimate the bearing angle shown in Fig. 2. The bearing estimate is given by the approximate rule s = cos-1 (&L) (2)
