摘要：
This paper studies the range equation modeling of a ground moving target for distributed multichannel medium Earth orbit synthetic aperture radar (SAR) ground moving target indication (GMTI). A third-order approximated range equation for each channel is established. Then, the range equation is simplified, and a more concise range equation model is derived, which will benefit the design of SAR-GMTI methods. Finally, through numerical simulation, the derived range model's accuracy and scope of application in different baseline lengths and wavelength bands are studied.
