Differential Correction Method of Long-Wave Propagation Time Delay Applied to Complex Long-Distance Path

IEEE Antennas and Wireless Propagation Letters
The precision of the long-wave propagation time delay is the key factor affecting the accuracy of land-based long-wave navigation timing systems. For the complex long-distance propagation path, a differential correction method of long-wave propagation ...

Waveguide for air-coupled ultrasonic phased-arrays with propagation time compensation and plug-in assembly.

Journal of the Acoustical Society of America, 2021
Waveguides allow grating lobe free beamforming for air-coupled ultrasonic phased-arrays by reducing the effective inter-element spacing to half wavelength. Since the sound waves propagate through the waveguide ducts, additional time delays are introduced.
