Shortly after 0000 UTC 22 September, Usagi's center entered the Doppler range
(230 km) where the axisymmetric kinematic structure, vorticity, and pressure deficit can be deduced from the GBVTD methodology (Lee et al.
As it can be seen trapezoidal pulse has much lower sidelobes in Doppler range
A new request-to-exit sensor from GE Security of Bradenton, Florida, combines Doppler Range
Controlled Radar motion sensing and Fresnel lens passive infrared (PIR) technologies.
The acquisition process for each code period is stepped in the Doppler range
in 500 Hz frequency increments.
But note that five ambiguities exist in the high-PRF pulse Doppler range
and three or four in the medium-PRF pulse Doppler range
