雷达网航迹欺骗干扰协同规划技术∗

摘要

空时协同是实施雷达网虚假航迹欺骗干扰的关键技术，也是面临的实际困难之一。针对这一问题，提出了一种基于集中航迹规划和分布航迹协同的雷达网航迹欺骗干扰技术。首先，在基准雷达极坐标系内设计基准航迹，然后将基准航迹转化到地心直角坐标系（ Earth⁃Centred， Earth⁃Fixed，ECEF）内，得到统一坐标系下的基准航迹。由于干扰设备须在雷达极坐标系内进行参数标定，因此将基准航迹转化到各雷达极坐标系内，完成空间上的航迹规划。而后通过干扰设备上的GPS模块对启动时间进行统一，并对基准航迹进行插值，计算出虚假航迹与雷达扫描的交汇点，完成时间上的统一，最后由干扰设备释放干扰，由此融合中心得到空时高度相关的上报航迹，容易将其误判为一条虚假航迹。试验结果验证了该方法的可行性、实用性。%Space⁃time alignment is one of the key technic to implement phantom tarck deception for radar network. In view of this problem, a collborative programming method based on centralized phantom track programming and distributed track collaboratting is proposed. Firstly, a benchmark phantom track is designed in benchmark radar polar coordinate system, then the benchmark track is transformed to Earth⁃Centred Earth⁃Fixed( ECEF) coordinate system. With the fact that the parame⁃ters of Jamming Equipment are demarcated in radar polar coordinate system, it is necessary that the benchmark track should be transformed to other radar polar coordinate system, here space alignment is finished. Then with the help of GPS module, the starting time is unified, and in order to accomplish time alignment, the phantom track is extrapolated to calculate the in⁃tersectting point. Lastly, the phantom track is released by Jamming Equipment, then the fusion center gain Space⁃time highly collborating track. Experimentation results verify the correctness of the method.
