WebOptimum bearing and range estimators are presented for the planar problem and related to the optimum time delay vector estimator. Suboptimum realizations are considered together with the effects of source motion and receiver positional uncertainty.
WebTime delay estimation (TDE) is commonly performed in practice by crosscorrelation of digitized echo signals. Since time delays are generally not integral multiples of the sampling period, the location of the largest sample of the crosscorrelation function (ccf) is an inexact estimator of the location of the peak. WebSep 9, 2011 · An algorithm is proposed for passive bearing estimation where the number of sources and their source signals are considered unknown in the presence of noise. An unknown but limited number of targets is assumed to be distributed in bearing (look angle) with unknown bearings and magnitudes.
