Based on the FDOA (frequency difference of arrival) location of the radiative source using moving observations

an FDOA location algorithm which solves the location of the target directly is proposed

which overcomes the difficulty in solving FDOA location algorithm.The proposed algorithm utilizes the polar coordinates to express the target coordinate relative to reference station

the algorithm uses the form of the FDOA location equation with skill

firstly

calculates the azimuth of the target

and then solves the radial range between the target and reference station

finally the equation with which the accurate location of the target can be determined directly is obtained.In this paper

an elaborate analysis of the algorithm is given

the ambiguity of azimuth and radial range as well as the solving method are discussed

simultaneously

simulation analysis shows that the theoretical analysis is correct

which provides the application of FDOA location algorithm with theoretical basis.
