This paper focuses on the effect of arbitrary transmitted waveform on clutter characteristics for airborne MIMO radar. Transmit waveform synthesis model is established by the transformation for signal space and sensor space. The uniform model of space time clutter is presented for airborne MIMO Radar, and the relation ship between signal waveform synthesis and the uniform model is expatiated. Clutter characteristics are analyzed in the simulations for arbitrary waveforms including coherent, correlated and orthogonal waveforms. It is found that the degree of clutter broaden is determined by the structure of signal cross-correlation matrix, and the clutter degree of freedom (DOF) is determined by the rank of the cross-correlation matrix. The uniform model is the foundation for the design of STAP algorithm.
