| 摘要: |
| 非合作双基地雷达在目标探测的安全稳健等方面展现了优越的性能。本文首先从双基地雷达同步这一关键问题出发，分析合作和非合作双基地雷达的差异，推导非合作双基地雷达目标定位原理。进一步设计非合作双基地雷达系统，解决时空同步问题，提取直达波和目标散射波的特征参数，解析两者路径差、接收方位、俯仰等信息，最终求解目标接收距离,实现目标定位。雷达协同探测试验采用实测数据验证了非合作双基地技术体制的可行性，为目标探测定位提供了有效的方法。 |

| Abstract: |
| Non?cooperative bistatic radar has demonstrated superior performance in terms of safety and robustness of target detection. This paper first focuses on the key problem of bistatic radar synchronization. Then, the differences between cooperative and non?cooperative bistatic radar are analyzed, and the target localization principle of non?cooperative bistatic radar is deduced. Furthermore, a non?cooperative bistatic radar system is designed, and the problem of space?time synchronization is solved. After that, the characteristic parameters of direct wave and the target scattering wave are extracted, and the information of the path difference, the receiving azimuth and the receiving pitch are analyzed. Finally, the target receiving distance is solved and the target positioning is achieved. The radar cooperative detection experiments on measured data show the feasibility of non?cooperative bistatic technology, which provides an effective method for target detection and positioning. |
