Abstract：In this paper,an improved elliptic ellipse center extraction algorithm based on stochastic sampling consistency method is proposed,which is too sensitive to noise and has poor anti-jamming performance in typical ellipse center extraction algo-rithms such as centroid method,Hough transform method and least squares fitting method. Simulation results show that the proposed algorithm has higher accuracy and strong robustness compared with the least square method and the centroid method.
