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 radar can reportedly manage up to 40 targets, monitor up to 10 of them in track-while-scan (TWS) mode and simultaneously fire on two BVR targets. [3] The detection range for targets with a radar cross-section of 3 square meters is stated to be ≥75 km (≥35 km in look-down mode).
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 ...
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.
The Bars-29 shares up to 90% of its software and hardware with the original Bars radar while being small enough to be installed within the nose of the MiG-29 fighter. [7] The Bars-29 has a detection range of 120 km against a target with an RCS of 5 m 2, 15 targets can be tracked at once when using track while scan mode, with 4 engaged at any ...
The fire-control radar must be directed to the general location of the target due to the radar's narrow beam width. This phase is also called "lighting up". [3] It ends when lock-on is acquired. Acquisition phase The fire-control radar switches to the acquisition phase of operation once the radar is in the general vicinity of the target.
To scan a portion of the sky, a non-PESA radar antenna must be physically moved to point in different directions. In contrast, the beam of a PESA radar can rapidly be changed to point in a different direction, simply by electrically adjusting the phase differences between different elements of the passive electronically scanned array (PESA).
