In this paper, an enhanced ranging method is proposed for an orthogonal frequency division multiplexing-based ranging system for space applications. In the proposed method, the classical multiple-signal classification algorithm is introduced and used to estimate the fractional part of the round-trip delay. Simulation results show that the proposed method can improve the estimation accuracy dramatically in the low signal-to-noise ratio regime.
