Analyses of a dust-devil dataset collected in northwest Texas are presented. The data were collected just above the ground at close range with a mobile, W-band, Doppler radar having an azimuthal (radial) resolution of 3-5 m (30 m) at the range of the dust devils. Most dust devils ...
A mobile, W-band Doppler radar scanned, at close range, portions of a tornado near Happy, Texas, on 5 May 2002. Simultaneous boresighted video images were also recorded, which facilitated correlating the radar-observed features of the tornado with its visual features. Range-height indicators (...
which compare the threshold signals to the quadrature signals. The comparators 212 are preferably implemented with high-speed CMOS circuits such as, for example, the TLC374 comparator chips distributed by Texas Instruments. The shift register 214, preferably formed from four 74HC4094 8 bit shift re...
The potential of microwave Doppler radar in non-contact vital sign detection is significant; however, prevailing radar-based heart rate (HR) and heart rate variability (HRV) monitoring technologies often necessitate data lengths surpassing 10 s, leading

(0,1) is interpreted by the DSP196as (−1,+1). Once the multiplies are performed, the summation of products is accomplished using a look-up table stored in EPROM. In the exemplary embodiment, the DSP196makes use of a Texas Instruments TMS320vc33 32-bit, digital signal processor chip....
Texas Tech University is responsible for two major observational platforms in VORTEX2. The first of these platforms is dubbed StickNet, an array of 24 in situ observation suites mounted on rugged engineering tripods. The primary aim of StickNet is to make measurements of thermodynamic and ...
