Abstract: Based on the fact that numerical integration can provide more stable and accurate results than numerical differentiation in the presence of noise, a constructive nonlinear velocity estimator ...
Abstract: We propose a method for measuring the instantaneous velocity of moving objects using ultrasonic waves. By transmitting and receiving a single dual-chirp pulse, composed of an up-chirp and a ...
This study conducted high-velocity penetration experiments using conventional ogive-nose, double-ogive-nose, and grooved-tapered projectiles of approximately 2.5 kg and initial velocities between 1000 ...
