About
Takashi Katagiri’s research centers on advancing ultrasonic sensing and signal processing for autonomous robotics, with a particular focus on enhancing distance measurement accuracy and resolution. His most-cited work, “Accuracy and resolution of ultrasonic distance measurement with high-time-resolution cross-correlation function obtained by single-bit signal processing” (2009, 48 citations), tackles a fundamental challenge in mobile robot environment recognition: improving the precision of time-of-flight (TOF) estimation. By applying pulse compression and single-bit signal processing to cross-correlation functions, Katagiri demonstrated how to achieve high-resolution distance measurements without sacrificing computational efficiency—a critical advancement for real-time robotic navigation. His contributions bridge the gap between theoretical signal processing and practical sensor design, enabling robots to perceive their surroundings with greater reliability. Beyond this landmark paper, his broader work explores the intersection of ultrasonic array processing and low-power embedded systems, making autonomous systems more responsive in cluttered environments. Katagiri’s research has influenced both academic studies in sensor fusion and industrial applications in robotics, where precise distance sensing remains a cornerstone of safe and efficient operation.
