38AN/FPS-16 — manned space program and the U.S. Air Force. The accuracy of Radar Set AN/FPS 16 is such that the position data obtained from point source targets has azimuth and elevation angular errors of less than 0.1 milliradian (approximately 0.006 degree)… …
39Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… …
40Pulse-Doppler radar — Pulse Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of …
