The output waveguide 14 transmits only a objective higher harmonic output and when operation as Doppler radar, guides a reflection wave from the object to the mixer diode 11 again. The reflecting wave from the moving substance receives Doppler shift and from the mixer diode 11 a frequency ...

Near out-of-distribution detection (OOD) aims at discriminating semantically similar data points without the supervision required for classification. This paper puts forward an OOD use case for radar targets detection extensible to other kinds of sensors and detection scenarios. We emphasize the relevanc...
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 (...
Designing the radar For radar applications high frequency is needed for smaller resolution. High frequency also allows using smaller antennas because wavelength is smaller. Unfortunately going to too high frequencies is going to get too expensive, component selection starts to be very limited and the ...
(2015) studied MSTIDs using the Super Dual Auroral Radar Network in Hokkaido, i.e., a location that is more poleward than Taiwan. Northeastward propagating MSTIDs were typical for summer and equinox. In Taiwan, we also observe northeastward propagating MSTIDs in summer; however, they are ...
The Doppler effect in an accelerating frame has various applications in different fields such as astronomy, acoustics, and radar technology. It is used to study the motion of stars and galaxies, measure the speed of objects in space, and in medical imaging techniques such as Doppler ultrasound....
The analysis at 1 GHz and 435 MHz of the person walking outside and near the forest allow us to draw preliminary conclusions. The radar system can detect and classify the retrieved signal of the walk regardless of the path, toward and from the antennas. The asymmetry of the activity, chara...
Currently, multichannel Doppler radar image is used for QPE based on some traditional methods like the Z − R relationship, which struggles to capture the complicated non-linear spatial relationship. Encouraged by the great success of using Deep Learning (DL) segmentation networks in medical ...
