Sensitivity time control (STC), also known as swept-gain control, is a system used to attenuate the very strong signals returned from nearby ground clutter targets in the first few range gates of a radar receiver. Without this attenuation, the receiver would routinely saturate due to the strong signals. This is used in air traffic control ...
A civil marine radar, for instance, may have user-selectable maximum instrumented display ranges of 72, or 96 or rarely 120 nautical miles, in accordance with international law, but maximum unambiguous ranges of over 40,000 nautical miles and maximum detection ranges of perhaps 150 nautical miles. When such huge disparities are noted, it ...
Proximity fuze MK53 removed from shell, circa 1950s. A proximity fuze (also VT fuze [1] [2] [3] or "variable time fuze") is a fuze that detonates an explosive device automatically when it approaches within a certain distance of its target.
In applied statistics, the Morris method for global sensitivity analysis is a so-called one-factor-at-a-time method, meaning that in each run only one input parameter is given a new value. It facilitates a global sensitivity analysis by making a number r {\displaystyle r} of local changes at different points x ( 1 → r ) {\displaystyle x(1 ...
The range resolution is the minimal range separation between two objects traveling at the same speed before the radar can detect two discrete reflections: = (). In addition to this sampling limit, the duration of the transmitted pulse could mean that returns from two targets will be received simultaneously from different parts of the pulse.
In radio technology, symmetrical double-sided two-way ranging (SDS-TWR) is a ranging method that uses two delays that naturally occur in signal transmission to determine the range between two stations: [1] Signal propagation delay between two wireless devices; Processing delay of acknowledgements within a wireless device
Honeywell said that it may calve its aerospace division from the conglomerate, sending shares up more than 2% before the opening bell Monday. The announcement arrives about one month after Elliott ...
