  2. Computational methods for free surface flow - Wikipedia

    en.wikipedia.org/wiki/Computational_methods_for...

    Computation in flows with free and moving boundaries like the open-channel flow is a difficult task. The position of the boundary is known only at the initial time and its location at later times can be determined as using various methods like the Interface Tracking Method and the Interface Capturing Method.

  3. 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.

  4. Volume of fluid method - Wikipedia

    en.wikipedia.org/wiki/Volume_of_fluid_method

    This approach was much simpler than other techniques tracking the surface of fluid, yet more versatile as it could model the coalescence and breakup of fluid regions. In 1976, Noh & Woodward [ 5 ] presented the Simple Line Interface Calculation (SLIC), a technique to approximate fluid interfaces based on volume fractions, designed for ...

    The moving particle semi-implicit (MPS) method is a computational method for the simulation of incompressible free surface flows. It is a macroscopic, deterministic particle method (Lagrangian mesh-free method ) developed by Koshizuka and Oka (1996) .

    en.wikipedia.org/wiki/EL/M-2052

    The Synthetic Aperture Radar (SAR) capabilities of the radar include high-resolution mapping, ground/surface moving target detection, and tracking using Real Beam Mapping (RBM), Doppler Beam Sharpening (DBS), in addition to Air to Ground Ranging (AGR). The radar system also provides long-range target detection and tracking, including target ...

    The Airport Movement Area Safety System (AMASS) visually and aurally prompts tower controllers to respond to situations which potentially compromise safety. AMASS is an add-on enhancement to the host Airport Surface Detection Equipment Model 3 (ASDE-3) radar that provides automated aural alerts to potential runway incursions and other hazards.

  8. Free-surface modelling - Wikipedia

    en.wikipedia.org/wiki/Free-surface_modelling

    In computational fluid dynamics, free-surface modelling (FSM) refers to the numerical modelling of a free surface—a freely moving interface between immiscible fluids—in order to be able to track and locate it. Common methods used in free surface modelling include the level-set method and the volume of fluid method

  9. AN/APS-154 - Wikipedia

    en.wikipedia.org/wiki/AN/APS-154

    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 areas. The radar was deployed on a small number of P-3C Orions, with "game changing" results.
