The aims of this work is to analyse the Cramer Rao lower bound (CRLB) for passive location of radio sources, as in multilateration (MLAT) systems and in their wide area version. The CRLB is used, in this paper, as the analysis method for the accuracy of position estimation using different measurements, related in a non-linear way to the target kinematics . The basic measurement is the classical TDOA...
The "multilateration" (MLAT) system is a surveillance and identification element of the A-SMGCS using the SSR transponder (Mode S or even A/C) reply/squitter as signals received by fixed stations where the time-of-arrival (TOA) is measured. In a central processing unit, the target position is estimated by the TDOA technique (time difference of arrival), for which a station is assumed to...
