This paper proposes a multi-transmitter and multi-receiver SAR imaging algorithm based on Kalman filtering. In the algorithm, the application of multi-transmitter and multi-receiver offer more information about the scene and unambiguous wide swath is achieved by reducing PRF. Orthogonal coding is used in multi-transmitter channels. Kalman filtering perfectly reconstructs the scene with fine resolution and the principle of MMSE resolves the problem of ambiguity caused by orthogonal waveforms. The proposed imaging algorithm is justified by theoretic analyses and validated by digital simulations.
