The drawback is that once the radar is set to tracking a single target, the operator loses information about any other targets. This is the problem that track while scan is meant to address. In traditional radar systems, the display is purely electrical; signals from the radar dish are amplified and sent directly to an oscilloscope for display ...
The AN/AWG-9 and AN/APG-71 radars are all-weather, multi-mode X band pulse-Doppler radar systems used in the F-14 Tomcat, and also tested on TA-3B. [1] It is a long-range air-to-air system capable of guiding several AIM-54 Phoenix or AIM-120 AMRAAM missiles simultaneously, using its track while scan mode.
In scanning mode, the radar can scan around a specified sector looking for any moving objects. It is also capable of "Track-while-Scan" (TWS) operation, and can track 50 targets in TWS acquisition mode. The speed of scan can also be adjusted by adjusting the speed of the antenna's rotation to either a low, medium or high rotational speed.
Track initiation is the process of creating a new radar track from an unassociated radar plot. When the tracker is first switched on, all the initial radar plots are used to create new tracks, but once the tracker is running, only those plots that couldn't be used to update an existing track are used to spawn new tracks.
Each array scans a given azimuth sector, providing a total coverage of 360°. Scanning is carried out electronically in both azimuth and elevation. Radar modes include high PRF search and full track, track-while-scan, a slow scan detection mode for hovering and low-speed helicopters (using rotor blade returns) and a low PRF ship detection mode.

The air-to-air modes included velocity search for long-range wide-angle searches, track-while-scan, single target track and dogfight modes that automatically locked onto the closest target. The APG-69 was capable of guiding the AIM-7 Sparrow missile, making it the first of Emerson's offerings to reach production with beyond visual range ...
The important modes of operation of the primary radar system are the surface surveillance and the air surveillance. The sensor has the abilities to search, track-while-scan, priority tracking, high performance tracking, etc. In priority tracking, the targets will be placed in full track mode even if these cross the primary surveillance area.
RAN-40L is based on existing land based 3D RAT-31DL radar which is a system widely used by NATO Countries for long air surveillance. [3] [4] The radar functions include Track While Scan for air and surface long-range surveillance and missile tracking . Radar coverage is obtained by phase scanning in elevation, while mechanically rotating in ...
