Abstract

Abstract:

Based on the FDOA and TDOA united location of the radiative source using moving observations, an iterative algorithm which solves the location of the target is proposed, which overcomes the difficulty in solving FDOA and TDOA united location. The proposed algorithm sets the carrier frequency as the unknown parameter, and under the condition of omitting the higher order items, the measured time difference and frequency equations are used to figure out both of the target position and carrier frequency from the emitter in the iterative way. The location accuracy of the TDOA and FDOA united location algorithm is analyzed in detail; furthermore, elaborative simulation is given, which proves the accuracy and effectiveness of the theoretical analysis and provides TDOA and FDOA united location algorithm with theoretical foundation.
