About

Zhenjing Yao is a leading researcher in advanced ultrasonic sensing and mobile robotics, with a focus on eliminating crosstalk interference to enable real-time, high-precision sonar systems. His major contributions center on developing novel modulation techniques that allow multiple ultrasonic sensors to operate simultaneously without signal interference—a critical challenge for autonomous navigation. In his most-cited work, "Real-Time Noncrosstalk Sonar System by Short Optimized Pulse-Position Modulation Sequences" (2009, 29 citations), Yao introduced optimized short PPM sequences that dramatically reduce false distance measurements while maintaining real-time performance. His earlier paper, "Non-crosstalk Real-Time Ultrasonic Range System with Optimized Chaotic Pulse Position-Width Modulation Excitation" (2008, 26 citations), pioneered the use of chaotic CPPWM sequences to create compact, non-interfering transmission codes. These innovations have significantly improved the efficiency and reliability of sonar arrays in mobile robots, enabling faster and more accurate environmental mapping. Yao’s work bridges theoretical signal design with practical robotic applications, making him a key figure in the evolution of intelligent sensing systems for autonomous platforms.
