Electronic harassment, electromagnetic torture, or psychotronic torture is the delusional belief, held by individuals who call themselves "targeted individuals" (TIs), that malicious actors are transmitting sounds and thoughts into people's heads, affecting their bodies, and harassing them generally.
A phenomenological model is a scientific model that describes the empirical relationship of phenomena to each other, in a way which is consistent with fundamental theory, but is not directly derived from theory. In other words, a phenomenological model is not derived from first principles. A phenomenological model forgoes any attempt to explain ...
Ground targets further than this range cannot be detected, so the PRF can be quite high; a radar with a PRF of 7.5 kHz will return ambiguous echoes from targets at about 20 km, or over the horizon. If however, the PRF was doubled to 15 kHz, then the ambiguous range is reduced to 10 km and targets beyond this range would only appear on the ...
When a target is within this range, the radar receives an adequate target skin return to track it. The burn through range is a function of the target RCS ( Radar cross-section ), jamming ERP ( Effective radiated power ), the radars ERP and required J/S (for the jamming to be effective).
The scattering of incident radar power by a radar target is never isotropic (even for a spherical target), and the RCS is a hypothetical area. In this light, RCS can be viewed as a correction factor that makes the radar equation "work out right" for the experimentally observed ratio of P r / P t {\textstyle P_{r}/P_{t}} .

Targeted surveillance (or targeted interception) is a form of surveillance, such as wiretapping, that is directed towards specific persons of interest, and is distinguishable from mass surveillance (or bulk interception).
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
