Theory and Observations Between Ka-Band and W-Band to Explain Scattering Differences from Insects
نویسنده
چکیده
Ground based Ka-band (33 GHz) cloud radar measurements collected at the Southern Great Plains (SGP) Cloud and Radiation Testbed (CART) site show that liquid cloud measurements are often contaminated by insect echoes during warm weather. Depolarization is one method of identifying and filtering insects from radar data. However, this technique often fails because the high number density of insects in the lower atmosphere overwhelm and mask the weaker cloud echos. It is impossible to tell whether clouds are present or not in such circumstances. Comparisons of measurements from Ka-band and W-band (95 GHz) radars with approximately equal sensitivity to clouds show that W-band is significantly less sensitive to insects.

Abstract- Design and simulation of a very small size 6-bit DMTL phase shifter is presented. The idea is based on using both capacitor and resonator type methods simultaneously in a phase shifter. The capacitor section creates less significant bits. The bits in this section start from the least significant bit, with 5.625-degree steps. The resonator section creates the bits with 90-degree steps....

Modern microwave and millimeter wave phased array antennas are attractive because of their ability to steer wave beams in space without physically moving the antenna element. A typical phased array antenna may have several thousand elements fed by a phase shifter for every antenna, which can steer the resulting array beam to different directions. Their low loss, low cost and lightweight phase s...
