Send us feedback. Reports from an Air Force Reserve Hurricane Hunter aircraft and National Weather Service Doppler radar data indicated maximum sustained winds were near 80 mph shortly after landfall, according to the NHC. Jennifer Sangalang, Austin American-Statesman, 8 July 2024 Also a nod to...
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 ...

The method of correlation is a technique well known from radar technology. Part of the Doppler signal is delayed by a known time τ: this is equivalent to adding a phase equal to the frequency multiplied by τ. The two signals, the original and the delayed one are compared in a cross-co...

Initially, the tracking gate supplied to the sample and hold circuit 20 may be produced at some preset value, for example near the outer most end of the range of the doppler radar. The signals supplied to the sample and hold circuit 20 from the video amplifier 16 are sampled once for ...
respectively. The low gain antennas are deployed near airport runways 40 and 42 where the invention may be advantageously used to detect winds, such as microbursts that might threaten aircraft. Of course, the invention might be employed anywhere one desires to use Doppler radar to monitor the ...
(ALEXANDRIA, VA, US) Claims: What is claimed is: 1. A Doppler radar apparatus comprising: a first oscillator for generating a first sweep signal to repeatedly sweep a predetermined frequency range periodically; a second oscillator for generating a second sweep signal having sweep properties ...
