| Abstract: | According to the time synchronization property of time division multip
le access(TDMA) system, three location algorithms are proposed based on the me
asurements of time of arrival (TOA) of TDMA moving target. The method of target
motion analysis (TMA) is used to analyse the observability condition of target p
osition and realize the TMA time difference of arrival (TDOA) location (TDOA-M
f
or short). Other two joint algorithms of conventional TDOA location (TDOA-C) and
TDOA-M with TMA ranging algorithm are presented. The proposed algorithms make f
ull use of the target motion property to improve location precision and avoid th
e phenomenon of multiple solutions and no solution. The simulation results illu
strate the validity of the proposed algorithms. |
