 | With the development of technology, Electronic Warfare has been increasing for decades its importance in modern battles. It can even be referred to as the heart of today's net-centric battlefield. Unmanned Aerial Systems are gaining more importance every single day. Nations are working on more complex and more effective UAS in order to accomplish missions that are very difficult, or even impossible for manned aircraft. Electronic Warfare missions are often ... |

 | The F-22 Raptor is a next-generation fighter-attack aircraft using the latest stealth technology to reduce detection by radar. Equipped with more advanced engines and avionics than the current F-15, the F-22 is expected to maintain U.S. Air Force capabilities against more sophisticated aircraft and missiles in the 21st century. In 1986 two contractors were selected to build competing prototypes: Lockheed's YF-22 and Northrop's YF-23, which were flight tested in late ... |

| Describes a countermeasure for LORO (lobe-on-receive-only) tracking radars comprising a transmitter and a receiver which controls the transmitter. The transmitter radiates pulses on the radar's frequency at a repetition rate that repeatedly sweeps over a range selected to include the unknown lobing frequency of the radar, the sweeps being alternately slow and fast. The receiver circuit receives the tracking radar signal and operates upon a fall in its intensity to ... |

| Many problems arise in radar and sonar applications which can be regarded as problems in detection theory or parameter estimation. Such problems have aspects of game theory associated with them when an intelligent opponent is assumed. This study concerns itself with the detection problem of radar and sonar where one is trying to distinguish between white noise and a short pulse signal imbedded in the white noise. The Doppler frequency ... |

| Military equipment and objectives can be masked from radio location observation through the use of special coatings. Absorption coatings must fulfill two requirements: they must not reflect electromagnetic waves and must absorb the waves originating in themselves. Rubber, polystyrol foam and other porous materials are suitable for such coatings. Mixtures of neoprene, carbon black,wool, iron filings and graphite are also suitable for damping wave reflection. |

|
| The apparent velocity of a false target from an interferer with pulse repetition frequency (PRF) equal to the victim system's PRF is found as a function of the oscillator instabilities of the two systems. The probability of track break as a function of oscillator instability, interference-to-signal ratio (I/S), and target velocity is found. (Author) |

| MINIMIZATION OF END-FIRE RADAR ECHO OF A LONG THIN BODY BY IMPEDANCE LOADING, |

| Authors:
Kun-Mu Chen; MICHIGAN UNIV ANN ARBOR RADIATION LAB
|
| A theory of the minimization of the end-fire radar echo of a long, thin body by an impedance loading technique is presented. When a long, thin body is illuminated by a plane wave in the region of longitudinal incidence, a large back scatter is observed. This back scatter is due to the induced traveling wave which is reflected from the rear end of the body. By an appropriate impedance loading, ... |

|
| This effort resulted in the successful development of an airborne false target repeater, covering essentially the entire 2000 to 4000 mc frequency range. This represents an eightfold increase of frequency coverage over the initial feasibility model, AN/ALQ-17 (XY-1) which had a bandwidth of but 250 megacycles. Two particular advantages of the system are immediately apparent. First, the repeater techniques employed result in transmission of false target signals at a frequency ... |
