摘　　要：基于传统雷达的有源定位和无源定位机理,构建了以雷达和接收设备组成的T/R-R双基地系统,根据系统结构选择两组最小测量子集,得到相应的目标位置解模型及定位误差协方差矩阵;然后给出了T/R-R双基地系统定位性能优化基本流程,并运用简化加权最小二乘(SWLS)算法优化相应的定位性能;最后仿真分析了T/R雷达站与T/R-R双基地系统的定位性能.仿真结果表明,与T/R雷达站相比,T/R-R双基地系统在提高定位性能的同时还具备一定的抗干扰能力.Based on the traditional radar’s active and passive positioning mechanism,this paper constructs the T/R-R dual-base radar system consisting of radar and receiving equipment,and according to the structure of the proposed system,selects two minimum measurement subsets to obtain the corresponding target position solution model and the positioning error covariance matrix.And then the paper gives the basic process of the positioning performance optimization of T/R-R dual-base system,and optimizes the corresponding positioning performance by using the simplified weighted least squares(SWLS)algorithm.Finally through simulation,the paper makes an analysis on the positioning performance of the T/R radar station and T/R-R dual-base system.The simulation results show that compared with the T/R radar station,the T/R-R dual-base system has certain anti-interference capability while improving the positioning performance.
