"   Very high angular resolution laser beam rider detector having a gated image intensifier and a video cameraDocument Type and Number:United States Patent 5280167Link to this page:<a href="http://www.freepatentsonline.com/5280167.html">http://www.freepatentsonline.com/5280167.html</a>Abstract:A laser warning receiver (LWR) having an ability to not only detect a low power level laser source, such as a pulse train emitted by a laser beam rider, but to also provide a high angular resolution in determining the angle of arrival of that pulse train. The receiver includes a lens/filter arrangement for a large area photodetector to detect an incoming signal from an emitting source and a high gain amplifier to amplify the signal which is then applied to a synchronization generator that generates a digital pulse train with pulses corresponding to peaks in the incoming signal. The digital pulse train is applied to a code breaker where the code is analyzed and a further code is generated anticipating the arrival of further pulses in order to verify the code. That further code is applied to a time gate generator which generate a code, synchronized with the incoming signal, that controls the high voltage of a gated image intensifier which is coupled to a video camera. Gating of the image intensifier is synchronized, as a result, with coded emissions from the source so that a video image from the camera can be displayed on a monitor and more easily differentiated from the background. The width of pulses generated by the time gate generator, the video camera, gain of the gated image intensifier, gain of the gated image intensifier and an auto-iris zoom lens coupled to the image intensifier are all under the control of a video processor."en cuanto al funcionamiento de los LBR:"   Scanning beam beamrider missile guidance systemDocument Type and Number:United States Patent 4516743Link to this page:<a href="http://www.freepatentsonline.com/4516743.html">http://www.freepatentsonline.com/4516743.html</a>Abstract:A beamrider guidance system for missiles wherein a laser beam is given two circular motions around the boresight axis to produce amplitude and phase modulation on the signal received at the missile. The information on distance from boresight is contained in the amplitude modulation and the angular information is contained as phase modulation. A laser optical system with a spinning holographic element provides one of the circular motions for the beam. The other circular motion is provided by a low frequency, circular scanning mirror."Como dice Rumple sólo existe la estabilización en dos ejes: horizontal y vertical.Es la desventaja de usar Kornet-E y demás ATGMs rusos de guía SACLOS.los resultados:Varios cientos de Merkavas desplegados en el sur del Líbano, un 10% alcanzados por fuego enemigo (incluyendo no sólo ATGMs sino minas e IEDs). De ese 10% sólo 18 Merkavas seriamente dañados, y dentro de esos 18 sólo 2 destruídos y ambos debido a sendos ataques por IED. Por cierto, en Líbano los de Hezbolá se dieron cuenta que el frontal del Merkava era casi impenetrable para los Kornet-E, teniendo que apuntar sus disparos a los ángulos traseros, laterales y superiores del CC a fin de asegurar penetraciones. Por cierto frontal que no debe ser muy diferente del que puedan tener los M1A2/SEP/TUSK/M1A1HA+ o incluso inferior al de los Leopard-2E/HEL.El Lahat utiliza laser porque se dispara desde CCs, donde sí o sí es necesario lasear para señalar el blanco, una vez hecho esto es lo mismo porque el misil toma una trayectoria balística que le permite penetrar el techo del objetivo, siendo de veradero interés, pues la dirección que pueda señalar el LWR en todo caso apuntal cielo.Más de lo mismo para las MRM. No son ATGMs convencionales sino munición de alcance extendido para los CCs, el objetivo de los MCM era extender el radio letal de los Abrams a 7.5-8.7kms más allá del alcance visual. El sistema utiliza un sistema de guía GPS/Láser/ondas milimétricas y el resultado es el mismo, el misil será detectado pero el vehículo lanzador no, ya que la señalización es llevada a cabo por agentes externos como UAVs.Es decir, que te pido fuentes y me cuelgas la página principal de un foro???? ...en fin.Sí seguramente esté peor protegido un C2 que un T-72M1 (ajajaja)..."The nearest unit with Javelin anti-tank weapons was Bushmaster, west of the overpass, protecting the Task Force northern flank. A four-man team armed with Javelins climbed onto the overpass to engage the tank. Less than 1 kilometer from the Tactical Operations Center, three T-72 tanks sat on a road, concealed by the wall to the Task Force's south. Unknown at the time, these tanks were not the ones firing at the overpass and Tactical Operations Center.Private First Class Davis engaged the lead tank, parked within feet the second tank. The Javelin screamed off the overpass, buzzing the Tactical Operations Center, and slammed directly into the top of the clueless T-72 with deafening thunder, entirely consuming the tank in a fireball and sending the heavy turret, end over end, more than 50 feet into the air. Secondary explosions complimented the initial blast as the internal ammunition storage compartment ignited. The fire reached out from the burning tank engulfing its neighbor and causing more explosions.To ensure complete catastrophic destruction of the second tank, Private First Class Davis fired a second Javelin, causing even more explosions on the second tank. At this point the third T-72 began frantically trying to determine the source and direction of incoming fire. Private First Class Jiminez engaged the now moving third tank. His round missed but impacted close enough to damage the tank. The tank limped away to meet its fate elsewhere.Minutes earlier, an amazing series of events unfolded with the mortars. While conducting a hasty dismount security patrol Captain Paul and Sergeant Adorno walked down the road leading south from Four Corners. It was the road the Task Force used earlier to enter the airport. An hour earlier, the B24 M1 broke down entering the airport. Under order from the battalion XO B22 pulled back to recover the disabled tank. As they drove into the airport they encountered Captain Paul on his patrol and asked where the maintenance collection point was located. Captain Paul directed the tanks to Four Corners.Less than 10 seconds later the ground rumbled again and Captain Paul and Sergeant Adorno turned to move out of the way, both instinctively raising their hands to wave as they turned. Shock and horror gripped the two as they realized they were waving at a pair of Iraqi T-72 tanks. Luckily, surprise and confusion also slowed the Iraqi tanker's reaction.
