During this phase, the radar system searches in the designated area in a predetermined search pattern until the target is located or redesignated. This phase terminates when a weapon is launched. Tracking phase The fire-control radar enters into the track phase when the target is located. The radar system locks onto the target during this phase.
Once the radar can "look down", it is subsequently desirable to "shoot down". Various weapons systems (including guns and missiles) are then employed against designated radar targets, either relying on the aircraft's radar employing the "look down" capability (as in semi-active radar homing) or the weapon's own active radar to resolve the indicated target (as in active radar homing).

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.
Track history for underwater objects can extend back several weeks. Each different kind of sensor produces different kinds of track data. A 2D radar with a fan beam produces no altitude information. A 4D radar with a pencil beam will produce radial Doppler velocity in addition to bearing, elevation, and slant range.
The antenna uses phase-frequency electronic scanning technology, forming sharp 3D pencil beams covering large surveillance and track volume. It uses a rotating platform with a high scan rate (30 RPM) to provide 360 degree coverage. The radar is designed with high resistance to electronic countermeasures (ECM) and anti-radiation missiles (ARM). [1]
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 ...
Volumetric Imaging and Processing of Integrated Radar, known by the acronym VIPIR, is an analysis and display program for Doppler weather radar, created and sold by Baron Services. [1] This software allows improved analysis of radar data for private users, in particular television stations, similar to the Weather Decision Support System program ...
