Target localisation in presence of multipaths
Hing Cheung So, P.C. Ching · Electronics Letters · 1993
A delayed version of a bandlimited signal can be represented by convolving a sine function and the signal itself. By using this property, a novel constrained LMS algorithm that estimates the difference in the arrival times of signals at two spatially separated receivers with multipath propagations is developed. The time delay obtained can be used to localise targets in sonar and radar systems.
