Which mode is not a pulse repetition time mode of the AN/TPS-75?

The configuration of the AN/TPS-75 radar system includes several pulse repetition time modes that dictate how the radar emits pulses and receives returns. Staggered, Burst, and Beacon modes are all specifically designed to enhance detection capabilities and manage the timing of radar signals effectively.

Staggered mode varies the timing of radar pulses to minimize clutter and provide better target resolution. Burst mode sends pulses in rapid succession, allowing for enhanced detection of fast-moving objects. Beacon mode typically involves sending continuous signals at specific intervals, allowing it to function as a navigation aid or to maintain contact with friendly units.

Desquint mode does not fit within the categorization of pulse repetition time modes for the AN/TPS-75. Instead, it relates more to the manipulation of radar beam direction or processing techniques aimed at refining target detection, rather than being a distinct timing pattern for pulse emission. Thus, identifying it as not fitting the criteria of a pulse repetition time mode clarifies its function and differentiates it from the other operational modes.
