Abstract
For the purpose of estimating location and velocity of moving target in three satellites system,a solution is presented for emitter passive location and velocity estimation using time-difference-of-arrival (TDOA) and frequency-difference-of-arrival(FDOA). Principles and process steps of the solution are described. The influence of TDOA measurement error,FDOA measurement error and altitude estimate error on location accuracy and velocity estimation accuracy is analyzed by Satellite Tool Kit( STK) and computer simulation. The proposed solution is accurate and efficient in locating and velocity estimating,which can be easily applied in engineering.关键词
