摘要

Orthogonal Frequency Division Multiplexing (OFDM) is an efficient modulation method which is widely used in many mobile communication systems. Applying OFDM signals to radar systems will make the combination of radar and communication systems in one single system platform possible. In this paper, the auto-correlation and cross-correlation components of the ambiguity function are researched for the analysis of the performance of the OFDM signal resolution. The impact of sparse subcarriers on the resolution of the delay and the Doppler is also discussed. Finally, the conclusions are verified.
