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.
AN/APG-65 radar installed in an F/A-18 Hornet. The APG-65 was developed in the late 1970s and has been operational since 1983. The radar includes a velocity search (to provide maximum detection range capability against nose aspect targets), range-while-search (to detect all-aspect targets), track-while-scan (which, when combined with an autonomous missile such as AIM-120, gives the aircraft a ...
DFR7. This low-cost detector has impressive range and all the requisite features, including GPS for low-speed false-alert muting, manual marking of up to 100 known radar locations, and speed ...
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.
In radar technology and similar fields, track-before-detect (TBD) is a concept according to which a signal is tracked before declaring it a target. In this approach, the sensor data about a tentative target are integrated over time and may yield detection in cases when signals from any particular time instance are too weak against clutter (low signal-to-noise ratio) to register a detected target.
Sensors (radar) scan a volume of space periodically. As an example, a capture distance of 10 miles require periodic scans no more than 15 seconds apart in order to detect vehicles traveling at mach 3. This is a performance limitation for non-Doppler systems. Transition to track begins when the capture volume for two detections overlap.
