【摘要】：研究了提高射频仿真系统的角度精度的方法。提出了三元组分集技术,该技术通过使用多个三元组同时对同一个点目标进行模拟来提高仿真角度精度。不同三元组具有相互独立的角度误差的电磁能流在空中汇集,称之为空间合并。当各三元组的能流配以合适的权重时,空间合并会给出最佳的角度精度。该文依据最大比率合并算法,给出了各三元组的最佳权重。当5个三元组进行分集时,仿真角度误差的方差可以减小到原来的60%以下。参与分集的三元组数目越大,仿真角度精度越高。这对于进一步提高三元组射频仿真精度具有理论意义和实用价值。
[Abstract]:The method to improve the angle accuracy of RF simulation system is studied, and the ternary diversity technology is proposed. This technique can improve the angle accuracy of simulation by using multiple triples to simulate the same point target simultaneously. The electromagnetic energy streams with independent angle errors among different triples gather in the air. Space merging is called spatial merging. When the energy flow of each triple is matched with appropriate weights, the space merging will give the best angle precision. In this paper, the maximum ratio merging algorithm is used to solve the problem. The optimum weight of each triple is given. When five triples have diversity, the variance of simulation angle error can be reduced to less than 60%. The higher the accuracy of simulation angle is, the more theoretical and practical value it is for further improving the accuracy of radio frequency simulation of triples.
