2. Blip-to-scan ratio - Wikipedia

   en.wikipedia.org/wiki/Blip-to-scan_ratio

   In this image, the yellow surface represents the lowest angles the radar can aim, based on the need to avoid reflections from the local terrain. The purple surface is the maximum angle the antenna can reach, often around 30 to 45 degrees. The red surface is the maximum range of the radar, which is a factor of many design decisions.

3. Imaging radar - Wikipedia

   en.wikipedia.org/wiki/Imaging_radar

   Imaging radar is an application of radar which is used to create two-dimensional images, typically of landscapes. Imaging radar provides its light to illuminate an area on the ground and take a picture at radio wavelengths. It uses an antenna and digital computer storage to record its images.

4. Track while scan - Wikipedia

   en.wikipedia.org/wiki/Track_while_scan

   Track-while-scan (TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets (up to forty with modern radar) while part of its power is allocated to scanning. [1]

5. Plan position indicator - Wikipedia

   en.wikipedia.org/wiki/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. It is the most common type of radar ...

6. Radar display - Wikipedia

   en.wikipedia.org/wiki/Radar_display

   An airport surveillance radar display. 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.

7. High Resolution Wide Swath SAR imaging - Wikipedia

   en.wikipedia.org/wiki/High_Resolution_Wide_Swath...

   Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details. In stripmap mode (spatial resolution of 3m), it needs 10 weeks to map global Earth's landmass.

9. Mini-automatic radar plotting aid - Wikipedia

   en.wikipedia.org/wiki/Mini-automatic_radar...

   Mini-automatic radar plotting aid (or MARPA) is a maritime radar feature for target tracking and collision avoidance. Targets must be manually selected, but are then tracked automatically, including range, bearing, target speed, target direction (course), CPA (closest point of approach), and TCPA (time of closest point of approach), safe or dangerous indication, and proximity alarm.
