  2. Moving target indication - Wikipedia

    en.wikipedia.org/wiki/Moving_target_indication

    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.

  3. Butterfly effect - Wikipedia

    en.wikipedia.org/wiki/Butterfly_effect

    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.

  4. Lorenz system - Wikipedia

    en.wikipedia.org/wiki/Lorenz_system

    This procedure later became known as a Lorenz map (not to be confused with a Poincaré plot, which plots the intersections of a trajectory with a prescribed surface). The resulting plot has a shape very similar to the tent map. Lorenz also found that when the maximum z value is above a certain cut-off, the system will switch to the next lobe ...

  5. Radar scalloping - Wikipedia

    en.wikipedia.org/wiki/Radar_scalloping

    Radar scalloping for MTI radar begins to become a concern when the radial velocity is greater than the following value. V e l o c i t y > 0.5 × ( C 2 × P e r i o d B e t w e e n P u l s e s × T r a n s m i t F r e q u e n c y ) {\displaystyle Velocity>0.5\times \left({\frac {C}{2\times PeriodBetweenPulses\times TransmitFrequency}}\right)}

  6. Radar horizon - Wikipedia

    en.wikipedia.org/wiki/Radar_horizon

    The antenna for radar with no signal processing clutter-reduction improvement is not normally aimed near the ground to avoid overwhelming computers and users. Moving Target Indication (MTI) can reduce clutter by about 35 dB. This allows objects as small as 1,000 square feet (93 m 2) to be detected.

  9. Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Doppler_radar

    A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
