摘　　要：本文提出一种描述双基机载雷达与杂波散射点几何关系的精确数学模型。文中详细分析了双基机载雷达与杂波散射点在不同场景下的几何关系,并推导了精确的数学表达式来描述这一关系。该模型并未对接收机、发射机的位置坐标加以限制,从而保证了这一几何模型可以适用于任意双基场景下。最后验证了该模型的正确性。An accurate mathematical model which expresses the geometrical relationship between the bistatic radars and the clut- ter scatterers is presented in this paper. The paper formulates mathematical expressions to describe the geometrical relationship basing on detailedly analyzing the geometrical relationship between the bistatic radars and the clutter scatterers in varying geometrical scenarios. There is no constraint condition on the position coordinates of the transmitter and the receiver. Thus the model can be applied in any geometrical scenarios. Finally, the model is examined by simulation.
