The AoA can be calculated by measuring the time difference of arrival (TDOA) between individual elements of the array. Generally this TDOA measurement is made by measuring the difference in received phase at each element in the antenna array. This can be thought of as beamforming in reverse. In beamforming, the signal from each element is ...
The most important intercept was a conversation discussing on 29 July the pending Italian surrender, weeks before the event took place on 3 September 1943, giving the Germans time to plan the occupation of Italy and disarming of Italian soldiers. The interception potential thereafter decreased, as did the number of phone calls intercepted.

Bombsights, a feature of combat aircraft since World War I, were first found on purpose-designed bomber aircraft and then moved to fighter-bombers and modern tactical aircraft as those aircraft took up the brunt of the bombing role.
Friden made a calculator that also provided square roots, basically by doing division, but with added mechanism that automatically incremented the number in the keyboard in a systematic fashion. The last of the mechanical calculators were likely to have short-cut multiplication, and some ten-key, serial-entry types had decimal-point keys.
A service stripe is an embroidered diagonal stripe worn on the sleeve(s) of some military and paramilitary uniforms. In the case of the United States military, service stripes are authorized for wear by enlisted personnel on the lower part of the sleeve of a uniform to denote length of service. Service stripes vary in size and in color.
The Military Grid Reference System (MGRS) [1] is the geocoordinate standard used by NATO militaries for locating points on Earth. The MGRS is derived from the Universal Transverse Mercator (UTM) grid system and the Universal Polar Stereographic (UPS) grid system, but uses a different labeling convention.
When National Service was first introduced in Singapore in 1967, the physical fitness test included a 4.8 km (3.0 mi) run to be completed within 30 minutes, and the completion of a 9.6 km (6.0 mi) run within 70 minutes while wearing the skeletal battle order (a type of load-bearing equipment).
