摘　　要：火箭回收舱段的准确定位是实现运载火箭可重复使用的关键技术之一。针对运载火箭回收舱段飞行轨迹的特点,基于多站到达时间差(TDOA)无源定位原理,通过在回收舱段上加装主动辐射源设计了火箭回收舱段定位系统。将时差非线性定位方程求解问题转化为时差似然函数的极值优化问题,通过引入量子编码理论、混沌映射和遗传反向学习机制改进海鸥算法(SOA),将其用于搜索回收舱段最优定位信息。仿真结果表明:改进的量子海鸥算法在火箭回收舱段定位解算的早期收敛速度、定位精度、全局搜索能力等方面均优于传统Chan算法和标准海鸥算法。The accurate location of launch vehicle recovery cabin is one of the key technologies to realize reusable launch vehicles.According to the characteristics of the flight trajectory of a launch vehicle recovery cabin,the positioning system of the launch vehicle recovery cabin is designed by adding an active radiation source on the recovery cabin and based on the passive positioning principle of multi-station time difference of arrival(TDOA).Then,the solving problem of the TDOA nonlinear location equation is transformed into the extreme value optimization problem of the TDOA likelihood function.The seagull optimization algorithm(SOA)is improved by introducing the quantum coding theory,chaotic mapping,and genetic reverse learning mechanism for searching and recovering the optimal location information of the cabin.The simulation results show that the improved quantum seagull optimization algorithm(QSOA)is superior to the traditional Chan algorithm and the standard seagull algorithm in the early convergence speed,the positioning accuracy,the global search ability,etc.of the positioning solution of the rocket recovery cabin.
