| 摘 要： | 在空基双基地雷达系统配置下，建立了空基双基地雷达地杂波的等距离和椭圆环模型，分析了双基地杂波的地面反射特性、杂波的幅度起伏、杂波的频谱分布以及收发载机雷达的系统参数对空基双基地雷达地杂波的影响，导出了空基双基地雷达在指定距离门内地杂渡模型的表达式。仿真分析了空基双基地雷达在不同几何配置下的空时二维杂波谱以及空基双基地雷达地杂波的距离依赖性，为后续有关空基双基地雷达杂波抑制和信号处理技术的研究提供了条件。

| Abstract: | The model of iso-range ellipse of bistatic airborne radar is presented under the system configuration. The ground reflectivity characteristic, clutter amplitude change, clutter spectrum distribution and radar system parameters on the ground clutter are analyzed. The ground clutter expression at certain range gate is derived. The clutter spectrum and clutter ridge are simulated under different geometric configurations. The results suggest that the clutter ridge is sensitive to the iso-range. The model of the ground clutter is significant to realize the clutter suppression and signal processing. |
