摘要
诱偏导航一体化系统是通过空中转发器构建伪星座,播发可控时延信号实现对一定区域内来袭GPS制导武器的诱偏干扰,同时己方接收机通过捕获己方导航数据获得空中平台位置和时延,实现一定区域内的自身导航.在实现诱偏干扰的同时,以提高系统对目标区域的整体定位精度为目标,以区域映射和覆盖为约束,在系统短时间工作条件下,建立多目标规划及最小最大评价函数的布阵优化数学模型.运用乘子罚函数法进行模型的求解,并给出求解步骤.在系统长时间工作的条件下,基于非线性规化的方法,建立空中平台的运动模型.给出了二次规划二次约束运动模型的求解步骤,仿真结果证明了模型的有效性.
Area-mapping deceiving unites battlefield navigation integrative system is introduced to mislead GPS users through the pseudosatellites composed of distributed transmitters.At the same time,the self-users could utilize the signal to accomplish navigation and orientation by the compensatory method of time delay.To improve the precision of navigation,restriction of the area-mapping and area-cover,in the short working time,the embattling optimization model was established based on multi-object programming and minimax evaluation function.The model was resolved by cost-function.Then,the process of resolving was presented.In the long system working time,the transmitters＇ moving model was presented by the multi-object and non-linear programming method.The process of resolving the QCQP（quadratically constrained quadratic programming） model was proposed.In the end,the models were simulated.The validity of the models were validated by the simulate results.
