Modern radars generally perform all of these MTI techniques as part of a wider suite of signal processing being carried out by digital signal processors. MTI may be specialized in terms of the type of clutter and environment: airborne MTI (AMTI), ground MTI (GMTI), etc., or may be combined mode: stationary and moving target indication (SMTI).
The AR-320 is a 3D early warning radar developed by the UK's Plessey in partnership with US-based ITT-Gilfillan.The system combined the receiver electronics, computer systems and displays of the earlier Plessey AR-3D with a Gilfillan-developed transmitter and planar array antenna from their S320 series.
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.
Senate Majority Leader Chuck Schumer has requested that "special detection systems" be deployed in New York and New Jersey after recent drone sightings fueled anxiety among residents in the region
The hundreds of mysterious New Jersey drone sightings are sparking mounting demands for a more forceful federal response, calls that come as even more sightings are being reported in New York ...
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.
Most people naturally have enough HGH. For those with a growth hormone deficiency (or a few other health conditions), GH therapy may offer a solution.
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 ...
