Abstract High resolution wide swath SAR requires high power aperture product under the limit of small antenna. It also needs generating and receiving wideband signal. According to these problems, a space-time-frequency coding method based on crossed receiving is presented in this paper. This method increases power by transmitting multiple sub-bands and multiple waveforms and overcomes the limits of power aperture product. It synthesizes wideband signal by the method of crossed receiving without complicated imaging algorithm. Finally simulations show its feasibility and validity.
