Collision, it is contended, is the mechanism which is necessary to investigate in order to better understand the launch conditions for saltation, creep transport and ripple formation, and surface re-sorting. Observations of landing and take-off veloc

Low-terahertz (THz) (above 150 GHz) radar sensing is one of the promising technologies to provide safe navigation for autonomous cars due to its expected high-resolution imaging capability. It is anticipated that for robust operation at high levels o

In this paper the capability of differentiating surfaces with different roughness characteristics by using bandwidths practical with low TeraHertz (low-THz) devices is discussed. The results presented show that the measured variance from a surface wi

Research to quantify the attenuation of 150 GHz and 300 GHz EM waves in sand has been conducted and the results are presented in this paper to investigate the performance of low-THz sensing for outdoor applications when an antenna radome might be con

In this paper the potential advantages of imaging outdoor environments in the low Terahertz (low-THz) range of frequencies (0.1 THz-1 THz) are discussed, in terms of the device parameters available at these frequencies and also in terms of the scatte

The measurements presented in this paper show that feature extraction can be used to identify objects of interest by making use of the scattering present and angular resolution available when using low TeraHertz (low-THz) (0.1 THz-1 THz) devices. The

Intensive research and development activity on low-terahertz (0.1–1 THz) electronics, including recent advances in monolithic microwave integrated circuit (MMIC) fabrication, indicate that THz radar might become feasible in the coming decade, at a

This paper proposes that the changes which occur in composition of the bed load during the transport of mixed-grain-size sediments are largely controlled by the distributions of critical entrainment shear stress for the various size fractions. This h
