An echo from a target will therefore be 'painted' on the display or integrated within the signal processor every time a new pulse is transmitted, reinforcing the return and making detection easier. The higher the PRF that is used, then the more the target is painted. However, with the higher PRF the range that the radar can "see" is reduced.
Track-while-scan (TWS) is a mode of radar operation in which the radar allocates part of its power to tracking a target or targets (up to forty with modern radar) while part of its power is allocated to scanning. [1]
The first radar of the radar family AN/APG-76 belongs to is AN/APQ-92, which equipped A-6A.AN/APQ-92 is a search and navigational radar, with function called search radar terrain clearance (SRTC) to generate a synthetic terrain display on the pilot's Vertical Display Indicator (VDI), which is a large cathode ray tube (CRT) display in the center of the pilot's console, right under the gun sight.
This mixing produces I(t) and Q(t). Phase coherence of the transmit signal is crucial for pulse-Doppler operation. In the diagram, the top shows phases of the wave-front in I/Q. Each of the disks shown in this diagram represent a single sample taken from multiple transmit pulses, i.e. the same sample offset by the transmit period (1/PRF).

Researchers from Mass General Brigham, a health care system in Boston, Massachusetts, shared with Fox News Digital some of the scientific developments and breakthroughs they expect to see in 2025.
In radar-engineering terms, while the target area is in the "far field" of the illuminating antenna, it is in the "near field" of the simulated one. Careful design and operation can accomplish resolution of items smaller than a millionth of the range, for example, 30 cm at 300 km, or about one foot at nearly 200 miles (320 km).
