AI Article Synopsis
- A new method has been created to extract human gait parameters from micro Doppler sonar grams, focusing on key metrics like walking speed and leg velocity.
- This technique is an adaptation of a previous radar data analysis method, due to the differences between sonar and radar data.
- The study analyzed data from 16 female and 60 male walkers, revealing that males generally have longer walk cycle times and higher peak leg velocities compared to females.
Article Abstract
An approach has been developed for extracting human gait parameters from micro Doppler sonar grams. Key parameters include average speed of walking, torso velocity, walk cycle time, and peak leg velocity. The approach is a modification of a technique previously used in radar data analysis. It has been adapted because of differences between sonar and radar micro Doppler grams. The approach has been applied to an acoustic data set of 16 female and 60 male walkers. Statistics have been tabulated that illustrate the similarities and dissimilarities between female and male gait. Males tend to walk with larger walk cycle times and peak leg velocities than females.
