Multiple extended target tracking based on distributed multi‐sensor fusion and shape estimation

2023 · IET Radar Sonar & Navigation

Abstract Distributed multi‐sensor fusion based on the generalised covariance intersection (GCI) fusion has been widely integrated into the Random Finite Set theory, which is promising for multi‐target tracking with an unknown number of targets. However, …

Study on a Method for Determining Fertilizer Type and Concentration Based on Fertilizer Dielectric Constant and Electrical Conductivity

2025 · Advances in Engineering Technology Research

The rapid detection of fertilizer solutions plays a crucial role in automated mixing or precise variable-rate fertilization. This paper proposes a method for detecting the type and concentration of single-element fertilizers. The experiment focuses on …
