Optimum passive bearing estimation
WebThe number of signals present is assumed to be finite, and each signal is parameterized by a finite number of parameters. Based on measurements of the array output, the objective is to estimate the signals and their parameters. This research area has attracted considerable interest for several years. WebOne goal of active-passive data fusion is to combine the complementary information collected by two types of sonar sensors to better perform signal processing. Active …

WebEstimates of arrival time intervals and their variation in time constitute basic measurement in a signal processor for undersea applications. Those measurements are then mapped in the data processor into the desired estimate of … WebAbstract: Passive sonar systems are used for estimating the range and bearing of signal sources, such as ships or submarines. In this study, the Cramer-Rao bounds on estimation errors are used as measures of the accuracy of the estimates. The bounds show how parameters such as observation time, signal bandwidth, signal-to-noise ratio, and array …

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. c2本能开什么车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. c2機関 未来WebThis paper seeks to find an optimum way of directing the resources of a passive horizontal line array when trying to estimate the direction of arrival (DOA), or bearing, of a contact. … dj jesliWebsignal has been detected, an important passive sonar problem is to estimate the time delay D between two sensors separated by length L.
