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 offers multiple air-to-air modes: long-range continuous-wave radar velocity search, range-while-search at shorter ranges, and an airborne track-while-scan mode with the ability to track up to 24 airborne targets, display 18 of them on the cockpit displays, and launch against 6 of them at the same time. This function was originally ...
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.
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.

Most modern radars have a track-while-scan capability, enabling them to function simultaneously as both fire-control radar and search radar. This works either by having the radar switch between sweeping the search sector and sending directed pulses at the target to be tracked, or by using a phased-array antenna to generate multiple simultaneous ...
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 ...
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.
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 ...
