Moving target indication (MTI) is a mode of operation of a radar to discriminate a target against the clutter. [1] It describes a variety of techniques used for finding moving objects, like an aircraft, and filter out unmoving ones, like hills or trees.
This is an issue only with a particular type of system; the pulse-Doppler radar, which uses the Doppler effect to resolve velocity from the apparent change in frequency caused by targets that have net radial velocities compared to the radar device. Examination of the spectrum generated by a pulsed transmitter, shown above, reveals that each of ...
A plot of Lorenz' strange attractor for values ρ=28, σ = 10, β = 8/3. The butterfly effect or sensitive dependence on initial conditions is the property of a dynamical system that, starting from any of various arbitrarily close alternative initial conditions on the attractor, the iterated points will become arbitrarily spread out from each other.
The radar is built by Raytheon as a follow-on to their AN/APS-149 Littoral Surveillance Radar System (LSRS). The AAS has its roots in the highly classified AN/APS-149 LSRS, which was designed to provide multi-function moving target detection and tracking and high resolution ground mapping at standoff ranges covering land, littoral , and water ...
In March, a mother was horrified to find a pedophile symbol on a toy she bought for her daughter. Although the symbol was not intentionally placed on the toy by the company who manufactured the ...
Scalloping is a radar phenomenon that reduces sensitivity for certain distance and velocity combinations. The name is derived from the appearance of areas that are scooped out of graphs that indicate radar sensitivity. Moving objects cause a phase-shift within the transmit pulse that produces signal cancellation.
Again, this isn't a common side effect. But if you’re experiencing negative mood or personality changes (or any other Ozempic side effects ), talk to your doctor ASAP, say both experts.
"In essence, this money has been stolen from all of us for all these years," said an 84-year-old woman whose late husband's Social Security benefits were slashed. "It's not fair."
