Effect of SGLT2 inhibitors on liver fat content: A meta-analysis Open

Qichao Ge, Fengling Zhang, Yong Liu · 2025

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major metabolic disorder linked to increased morbidity and mortality. Sodium-glucose co-transporter-2 (SGLT2) inhibitors, commonly used to manage type 2 diabetes (T2DM),…

High-Precision Mutual Coupling Coefficient Estimation for Adaptive Beamforming Open

Ziang Feng, Guoping Hu, Qichao Ge, Hao Zhou · 2020

Here, a high-precision mutual coupling coefficient estimation method is proposed that is more suitable for adaptive beamforming than traditional algorithms. According to the relationship between the designed transition matrix and the signa…

Research on Frequency Domain Filtering Method Based on Frequency Response Zero Control Technology Open

Chong Yan, Yongshun Zhang, Qichao Ge · 2019

Airspace adaptive beamforming has been widely used in radar anti-jamming. In this paper, by applying the appropriate model, the spatial adaptive beamforming method is applied to the time domain filtering to form an adaptive filter. For the…

Micro‐Doppler separation of multi‐target based on ACO in midcourse Open

Yizhe Wang, Yongshun Zhang, Cunqian Feng, Bin Chen, Qichao Ge · 2019

To solve the problem of mutual superposition and interference of multi‐target micro‐Doppler in midcourse, a method based on modified ant colony optimisation (ACO) is proposed. On the basis of building 3D time–frequency map, pheromone on ea…

Multi-mainlobe Interferences Suppression Based on Interference Covariance Matrix Reconstruction Open

Shuai Pan, Yongshun Zhang, Qichao Ge, Renrong Hu, Chong Yan · 2019

Here a novel eigen-projection matrix preprocessing (EMP ) technology in view of covariance matrix rebuilding is presented. The eigenvectors of multiple mainlobe interferences are calculated via the correlation of eigenvectors between the s…

Robust STAP Based on Training Snapshot Selection and Steering Vector Estimation Open

Zhihui Li, Yongshun Zhang, Yiduo Guo, Shuai Pan, Qichao Ge · 2019

The presence of mismatch between the presumed and actual target direction in spatial-temporal plane and the contamination of signal of interest (SOI) in training snapshots significantly degrades the performance of space-time adaptive proce…

A Non-side-looking Range Compensation Method for MIMO Radar Open

Yang Liu, Yongshun Zhang, Qichao Ge, Zhihui Li · 2017

The loss for degree of system freedom and mismatch of prior information based on registration based compensation method will result in a decline in the computation performance.In order to solve the above problems, an improved method is pro…

High-resolution direction-of-arrival estimation using Khatri-Rao product and spatial sparsity of sources Open

Shanshan Ding, Ningning Tong, Qichao Ge · 2016

Algorithms based on Khatri-Rao (K-R) product improve the degree of freedom (DOF) of virtual arrays and thus more source angles can be estimated.However, the estimation accuracy is not satisfying.In this paper, a method considering spatial …

Low-angle estimation method for meter-wave radar via matrix completion Open

Qichao Ge, Yongshun Zhang, Shanshan Ding · 2016

The deficiencies of array elements causes the decrease of angle survey precision when detect low-angle estimation.In order to solve this problem, this paper transform the data missing matrix which isn't meeting the condition of the SIP int…
