Multilateration apparatus

摘要

Abstract Multilateration Apparatus 5 In a multilateration apparatus a correlator is provided with a time of arrival correlation window which is set to cater for the path lengths that may be experienced before a signal from an object to be located is received by receivers in the system. This may be on the basis of the largest possible path length in the system or on a receiver by receiver basis. Figure 2 0 co 0Z 0C 0~Co
