天线方向图的天线罩赋形补偿
Science & Technology Vision（2014）
Abstract
针对天线罩对天线辐射电磁波的不均匀插入相位延迟使天线方向图发生了畸变，导致接收系统信号失真，在畸变方向上探测器灵敏度降低的问题，本文提出了天线罩赋形的方法，该方法通过修正天线罩内腔使通过天线罩的电磁波相位超前或滞后，结合天线罩的透射系数相位分布，使两者的相位差抵消，达到天线方向图的补偿，仿真和测试表明该方法有效的解决了天线方向图畸变导致的接收系统灵敏度降低的问题。

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
