| 摘 要： | 根据平移不变模式双基地合成孔径雷达的空间几何关系模型，分析了平移不变模式双基地合成孔径雷达点目标的距离徙动特性，并进一步推导出了平移不变结构双基地合成孔径雷达的距离聚焦深度计算公式。该式表明平移不变结构双基地SAR距离聚焦深度与双基地角、方位分辨力、收发分机波束指向和目标到飞机最近距离之比有关。最后通过仿真，验证了理论分析的正确性。

| Abstract: | The problem of translational invariant bistatic SAR range focusing depth was studied in this paper. Firstly, the geometrical model of translational invariant bistatic SAR was derived and its range migration characteristics were analyzed. Then the expression of translational invariant bistatic SAR range focusing depth was derived based on these. This expression shows that translational invariant bistatic SAR range focusing depth had relationship with bistatic angle, azimuth resolution, squint angles of trans... |
