  2. Water surface searches - Wikipedia

    en.wikipedia.org/wiki/Water_surface_searches

    Water surface searches are procedures carried out on or over the surface of a body of water with the purpose of finding lost vessels, persons, or floating objects, which may use one or more of a variety of search patterns depending on the target of the search, as the direction and rate of drift vary depending on the characteristics of the target and the water and weather conditions at the time.

  3. Fluctuation loss - Wikipedia

    en.wikipedia.org/wiki/Fluctuation_loss

    This model is particularly useful for considering aircraft shapes. Swerling I describes the case in which the target's velocity is low compared to the observation time, and can thus be considered non-moving. This is the case for a scanning radar, which sweeps its signal past the target in a relatively short time, often on the order of milliseconds.

  4. Range gate pull-off - Wikipedia

    en.wikipedia.org/wiki/Range_gate_pull-off

    In these systems, the operator would select a target using the strobe, and then circuits in the radar would automatically track the target in azimuth and elevation. This eliminated the need for the additional operators. Since the target's range would continue to change as it moved, the circuitry also attempted to keep the strobe centered in range.

  5. Point shooting - Wikipedia

    en.wikipedia.org/wiki/Point_shooting

    Side view of handgun point shooting position. Point shooting (also known as target-[1] or threat-focused shooting, [2] intuitive shooting, instinctive shooting, subconscious tactical shooting, or hipfiring) is a practical shooting method where the shooter points a ranged weapon (typically a repeating firearm) at a target without relying on the use of sights to aim.

  6. Underwater searches - Wikipedia

    en.wikipedia.org/wiki/Underwater_searches

    AUSS could do broad area searches and immediate target evaluation interchangeably, and could provide near-real-time high-resolution sonar data at speeds up to five knots. The vehicle could be instructed to take still images from specific locations, or to provide a photo-mosaic of a specified size, orientation, and location.

  7. Reservoir sampling - Wikipedia

    en.wikipedia.org/wiki/Reservoir_sampling

    The KLRS algorithm was designed to create a flexible policy that matches class percentages in the buffer to a target distribution while employing Reservoir Sampling techniques. This is achieved by minimizing the Kullback-Leibler (KL) divergence between the current buffer distribution and the desired target distribution.

  8. Predictive modelling - Wikipedia

    en.wikipedia.org/wiki/Predictive_modelling

    In many cases, the model is chosen on the basis of detection theory to try to guess the probability of an outcome given a set amount of input data, for example given an email determining how likely that it is spam. Models can use one or more classifiers in trying to determine the probability of a set of data belonging to another set. For ...

  9. Simulation-based optimization - Wikipedia

    en.wikipedia.org/wiki/Simulation-based_optimization

    Simulation-based optimization has some limitations, such as the difficulty of creating a model that imitates the dynamic behavior of a system in a way that is considered good enough for its representation. Another problem is complexity in the determining uncontrollable parameters of both real-world system and simulation.
