target in clutter
11ground clutter — An unwanted pattern produced on a radarscope caused by returns from the ground. This can degrade radar in that particular area where clutter is present. The effect of ground clutter can be minimized by use of MTI, or moving target indicator,… …
12radar — /ray dahr/, n. 1. Electronics. a device for determining the presence and location of an object by measuring the time for the echo of a radio wave to return from it and the direction from which it returns. 2. a means or sense of awareness or… …
13Radar — For other uses, see Radar (disambiguation). A long range radar antenna, known as ALTAIR, used to detect and track space objects in conjunction with ABM testing at the Ronald Reagan Test Site on Kwajalein Atoll …
14Radar MASINT — is one of the subdisciplines of Measurement and Signature Intelligence (MASINT) and refers to intelligence gathering activities that bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT),… …
15Radar signal characteristics — A Radar System uses a Radio Frequency electromagnetic signal reflected from a target to determine information about that target. In any radar system, the signal transmitted and received will exhibit many of the characteristics described below.The …
16Light pollution — This article is about light pollution in the visible spectrum. For information on pollution in the radio spectrum, see radio spectrum pollution. This time exposure photo of New York City at night shows skyglow, one form of light pollution …
17Pulse-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 …
18Iowa class battleship — The Iowa class battleships were a class of six fast battleships ordered by the United States Navy in 1939 and 1940 to escort the Fast Carrier Task Forces that would operate in the Pacific Theater of World War II. Four were completed in the early… …
19Constant false alarm rate — (CFAR) detection refers to a common form of adaptive algorithm used in radar systems to detect target returns against a background of noise, clutter and interference. Other detection algorithms are not adaptive. Non adaptive detectors are… …
20Missile Approach Warning — A Missile Approach Warning system is part of the avionics package on some military aircraft. A sensor detects attacking missiles. Its automatic warning cues the pilot to make a defensive maneuver and deploy the available countermeasures to… …
