Abstract
We generalize research on symmetric carrier frequency offsets for linear frequency diverse arrays by using a power law for parametric control of the resultant field. Use of a power law can destroy periodicity in range that facilitates measurement of range but we show that quantization of power law frequency offsets to a design frequency grid restores it and can simplify radar design and operation. We conduct element location and frequency offset sensitivity analyses using Gaussian and quadratic best-fit models for a notional linear array that suggest important uncertainty tolerances.

- 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
