Abstract

Abstract:

For the FDOA location scene of locating the fixed radiation source with a moving observation station, an algorithm based on the iterative method is proposed, which can be used to solve the problem of calculating the target position in the FDOA location. The proposed algorithm includes two situations, one with the carrier frequency known, and the other with the carrier frequency unknown. In the condition of the known carrier frequency, the measured frequency difference equation is used to figure out the target position in an iterative way; in the case of the unknown frequency, the measured frequency difference equation is used to figure out both the target position and carrier frequency from the emitter in an iterative way. The location accuracy of the FDOA location algorithm is analyzed in detail, and furthermore, an elaborative simulation is given, which proves the accuracy and effectiveness of the theoretical analysis, and provides the FDOA location algorithm with a theoretical foundation.
