Orthogonal Frequency-Division Multiplexing (OFDM) phase-coded radar has many prominent properties. However, there are some technical challenges on engineering realization, one of which is that instantaneous bandwidth is equal to the total bandwidth and large bandwidth leads to high requirement of the radar receiving technique. Aiming at this problem, a new radar signal named OFDM Phase-Coded Stepped-Frequency (OFDM-PCSF) signal is proposed. Several OFDM Phase-Coded (OFDM-PC) pulses with small bandwidth construct a pulse burst to synthesize large bandwidth, using stepped-frequency carriers. Based on deriving the ambiguity function of the new radar signal, the paper analyzes mainly the high range resolution and Doppler property. A conclusion is drawn that OFDM-PCSF signal can achieve high range resolution and the Doppler sensitivity is between the OFDM-PC pulse and the stepped-frequency signal.
