AI Technical Summary
In RSS testing, temporal and spatial accuracy are coupled, resulting in low evaluation effectiveness and insufficient reliability of the sensing system in the time dimension.
A spatiotemporal decoupling analysis method based on multidimensional trajectory features is adopted. By visually inspecting the data of the test equipment and the system under test, the instantaneous frequency and timestamp are analyzed, the error index is calculated, the time and space accuracy are decoupled, and the MTIE and TDEV indices are introduced to evaluate the frequency stability of the sensing system.
It enables accurate evaluation of RSS systems, improves the effectiveness of assessments and the reliability of the perception system in the time dimension, and provides methods for optimizing the perception system.
