Targets in a Low SNR Environment
Hemchandra Madhusudan Shertukde, Yaakov Bar‐Shalom · 1990
A detection and estimation technique for multiple targets with two omnidirectional sensors in the presence of false measurements was presented in [l]. This was done using the Track Before Detect (TBD) Approach. In this paper the Maximum Likelihood (ML] estimation of the time difference of arrival (TDOAI is analysed a nd its accuracy is expressed explicitly in terms of signal sampling interval ( resolution cell], the SNR and the number of samples in the data window used to generate a measurement. A preliminary performance validation is carried for a scenario with low SNR.
