The coupling among multiple coded orthogonal waveforms occupying the same frequency band may seriously affect the distributed terrain imaging of multiple‐input and multiple‐output synthetic aperture radar (MIMO‐SAR). Based on the inter‐pulse phase modulation among different transmitting waveforms, a range‐Doppler decouple filtering method is presented to separate waveforms effectively. Finally, numerical experiments are provided to demonstrate the effectiveness of the proposed method.
