A radar display is an electronic device that presents radar data to the operator. The radar system transmits pulses or continuous waves of electromagnetic radiation, a small portion of which backscatter off targets (intended or otherwise) and return to the radar system. The receiver converts all received electromagnetic radiation into a ...
Pocket Radar utilizes very similar microwave signal emission and detection methods found in the Doppler speed radar guns used by law enforcement agencies. The device measures 4.7 by 2.3 inches (119 by 58 mm) and weighs 4.5 ounces (130 g) when equipped with two AAA batteries. It operates at the 24.125 GHz K-Band frequency and can measure speeds ...
Surface search radar display commonly found on ships. Navigational radars resemble search radar, but use very short waves that reflect from earth and stone. They are common on commercial ships and long-distance commercial aircraft. Marine radars are used by ships for collision avoidance and navigation purposes.
Plan position indicator. A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point.
The constant altitude plan position indicator, better known as CAPPI, is a radar display which gives a horizontal cross-section of data at constant altitude. It has been developed by McGill University in Montreal by the Stormy Weather Group [1] to circumvent some problems with the PPI: Altitude changing with distance to the radar.
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. It contrasts with the modern stationary target indication (STI) technique, which uses ...
