Typical pulse as measured with THz-TDS. In physics, terahertz time-domain spectroscopy (THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation.
A tornadic debris signature (TDS), often colloquially referred to as a debris ball, [1] is an area of high reflectivity on weather radar caused by debris lofting into the air, usually associated with a tornado. [1] [2] A TDS may also be indicated by dual-polarization radar products, designated as a polarimetric tornado debris signature (PTDS).
"Camel" is a remotely controlled platform designed for various tasks, including enemy detection and elimination, equipment transport, reconnaissance operations, and destroying armored enemy targets. [18] In 2020, the platform was successfully tested at the State Research and Testing Institute for Weapons and Military Equipment Certification. [19]
The XM-2 personnel detector manpack, also known as the E63 manpack personnel detector, [3] was the first version of the people sniffer employed by the Army. The XM-2 featured a backpack mounted sensor with an air intake tube on the end of a rifle. The XM-2 was problematic, as it often detected the soldier carrying it rather than the enemy.
These sensors are networked devices that provide an early warning system to supplement a platoon size element and are capable of remote operation. To an extent T-UGS will detect, track, classify, and identify personnel and vehicles within its coverage area and report to the FCS Network in near real-time. T-UGS comprises the following sensor ...
Boomerang, a gunfire locator, being used by British forces in Afghanistan Shooting Detector Diagram. A gunfire locator or gunshot detection system is a system that detects and conveys the location of gunfire or other weapon fire using acoustic, vibration, optical, or potentially other types of sensors, as well as a combination of such sensors.
An aircraft identified as enemy, in accordance with theater ID criteria. The term does not necessarily imply direction or authority to engage. Banzai Information/directive to execute launch and decide tactics. Base (number) Reference number used to indicate such information as headings, altitude, and fuels. Bassett Rocket-thrown ASW torpedo ...
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output.
