摘要： Aircraft decoy arrangement and method for generating a decoy signal from an aircraft having an isolated decoy. An aircraft receiver detects a threat signal from a threat source targeting the aircraft. An aircraft signal processor produces a decoy relay signal based on the threat signal, where the decoy relay signal frequency is significantly lower than the threat signal frequency and is slowly attenuated through air, the signal processor calibrating the decoy relay signal in accordance with a received test signal to compensate for inaccuracies. An aircraft transmitter transmits the decoy relay signal and an optional reference signal to the decoy, where it is received by a decoy receiver, converted back to a decoy signal by a decoy frequency converter, and transmitted by a decoy transmitter, causing the threat source to detect the decoy signal and lock onto the decoy rather than the aircraft.

摘要： A tracking apparatus including a sensor tracker and a control tracker (60). The sensor tracker is connected to a sensor which senses a scene having at least one object therein, the sensor tracker provides sensor movement instructions to the sensor, enabling it track a selected object. The control tracker is located remotely from and communicates with the sensor tracker. Additionally, the control tracker takes measurements regarding the selected object and provides tracking instructions to the sensor tracker. The sensor tracker then utilizes the tracking instructions to adjust the sensor movement instructions, when necessary.

摘要： A method of laser treatment of surfaces comprises the steps of: I) projecting onto the substrate surface laser pulses defining a beam; II) causing said beam and said surface to become relatively displaced in such a way that said beam will intersect at each number of pulses, preferably at each pulse, an area of said surface that is different from and non-adjacent to the area the beam intersected before said displacement; and III) continuing to cause that the beam and said surface to be treated so to become relatively displaced, until all of said strips have thus been treated by the laser beam.

摘要： A method and a system for locating underground targets by using radar signals emitted from a radar transmitter coupled to a transmitter antenna, and echoed signals collected from a target by a radar receiver coupled to a transmitter antenna. The radar signals are collected via the receiver antenna which translates above ground along a closed course in cooperation with the transmitter antenna. The radar signals are processed in correlation with time and with a respective momentaneous location of the receiver antenna and the location of the transmitter antenna. The transmitter antenna is disposed on a land borne platform and the receiver antenna is disposed on the same land borne platform or on another land borne platform or on an airborne platform. The land borne platform and the airborne platform are selected as a mobile platform, a driver guided platform, a remotely guided platform, or an autonomously guided platform.

摘要： A device for extending the duration of a light pulse by a factor of an integer or by a factor which differs from an integer. The light pulse is passed through a device which divides the initial beam into a number of parts, where the first part passes unhindered while the subsequent parts of the beam are retarded and pass through the system after various delay periods, resulting in the desired extension of the pulse duration. The basic components of the novel device are spherical mirrors facing each other, a special reflector and a translation plate.
