1Radar jamming and deception — is the intentional emission of radio frequency signals to interfere with the operation of a radar by saturating its receiver with noise or false information. There are two types of radar jamming: Mechanical and Electronic jamming . Mechanical… …
2radar — /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… …
3Radar 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 …
4Radar navigation — Marine radar systems can provide very useful navigation information in a variety of situations. When the vessel is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted… …
5Radar detector detector — A radar detector detector (RDD) is a device used by police in areas where radar detectors are declared illegal.Radar detectors are built around a superheterodyne receiver, which has a local oscillator that radiates slightly. It is therefore… …
6Radar 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),… …
7Radar cross section — (RCS) is a measure of how detectable an object is with a radar. For example a stealth aircraft (which is designed to be undetectable) will have design features that give it a low RCS, as opposed to a passenger airliner that will have a high… …
8Range imaging — is the name for a collection of techniques which are used to produce a 2D image showing the distance to points in a scene from a specific point, normally associated with some type of sensor device.The resulting image, the range image , has pixel… …
9Radar astronomy — is a technique of observing nearby astronomical objects by reflecting microwaves off target objects and analyzing the echoes. This research has been conducted for four decades. Radar astronomy differs from radio astronomy in that the latter is a… …
10radar beacon — ☆ radar beacon n. a beacon with its transmitter and other components that emits radar waves for reception and display, indicating its range or bearing, or both, from a receiving set: it is usually a transponder that returns coded signals only… …
