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.

The system has two or three radar sub-systems depending on the model. The first two are combined into a single system called the Combined Antenna System or CAS is used in all models. The CAS has a track while scan radar (Search) and a tracking radar both housed in an egg shaped radome. The radars can search for, track, and illuminate targets.
Track algorithm operation depends upon a track file, which contains historical track data, and a computer program that periodically updates the track file. [ 3 ] Sensors information (radar, sonar, and transponder data) is provided to the track algorithm using a polar coordinate system , and this is converted to cartesian coordinate system for ...
James Alan Fox, a professor of criminology, law and public policy at Northeastern University, said that while vehicle rammings remain relatively rare among mass-casualty incidents in the United ...
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.
A judge told the parents of 27-year-old Ellen Greenberg, a Philadelphia teacher found dead with 20 stab wounds in 2011, that the city's declaration of suicide was "puzzling."
