Abstract :
A detection and estimation techniques multiple targets with two omnidirectional sensors in the presence of false measurements is presented. The maximum-likelihood estimation of the time difference of arrival is analyzed, and its accuracy is expressed explicitly in terms of signal sampling interval (resolution cell), the signal-to-noise ratio (SNR), and the number of samples in the data window used to generate a measurement. A preliminary performance validation is carried out for a scenario with a low SNR
