【摘要】：研究了提高射頻仿真系統(tǒng)的角度精度的方法。提出了三元組分集技術(shù),該技術(shù)通過(guò)使用多個(gè)三元組同時(shí)對(duì)同一個(gè)點(diǎn)目標(biāo)進(jìn)行模擬來(lái)提高仿真角度精度。不同三元組具有相互獨(dú)立的角度誤差的電磁能流在空中匯集,稱之為空間合并。當(dāng)各三元組的能流配以合適的權(quán)重時(shí),空間合并會(huì)給出最佳的角度精度。該文依據(jù)最大比率合并算法,給出了各三元組的最佳權(quán)重。當(dāng)5個(gè)三元組進(jìn)行分集時(shí),仿真角度誤差的方差可以減小到原來(lái)的60%以下。參與分集的三元組數(shù)目越大,仿真角度精度越高。這對(duì)于進(jìn)一步提高三元組射頻仿真精度具有理論意義和實(shí)用價(jià)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.
