Minimum Signal-To-Noise Ratio for High Classification Radar Accuracy
2023 30th IEEE International Conference on Electronics, Circuits and Systems (ICECS)（2023）
Abstract
Radar sensors in automotive cars are crucial for detecting and avoiding obstacles, improving safety, and enabling advanced driver-assistance systems. The signal-to-noise ratio (SNR) is a significant metric in radar systems for detecting the target at the output of the radar receiver and classifying the images in the algorithm classification. The purpose of this study is to determine the minimum SNR of images and signals to achieve high classification accuracy. A public dataset based on impulse radar and the LeNet-5 CNN architecture were used. The simulations demonstrated that images with an 10 dB of SNR can be classified with a high accuracy of 98%, and a 0 dB SNR at the output of the radar receiver was reported to be the minimum SNR required at the front-end output.

- 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
