Abstract: In a method for generating a transillumination signal of a section of the subsurface, an HPEM radiation source radiates an electromagnetic pulse into the section for the purpose of exciting electromagnetically reactive structures to emit an electromagnetic response signal. For the pulse, a pulse duration of at most 500 ns, a center frequency in the range between 10 MHz and 10 GHz, and a bandwidth in the range from 10% to 150% of the center frequency is set. The transillumination signal is formed as the sum of response signals received at a measuring location. In a method for detecting a cavity in the subsurface, the above method is carried out, and the structures are detected from the transillumination signal with the aid of a detection method, and the cavity is detected if the structures satisfy a detection criterion.

Abstract: The invention relates to a method for determining characteristic-curve correction factors a matrix detector that images in the infrared spectral range. A good image correction can be obtained by virtue of an area of homogeneous temperature being recorded at two different temperatures by the matrix detector, there being two images with different integration times for each temperature. A signal gradient over the integration time is established for each of the pixels from the four pixel values at the two temperatures in each case and the gain being established from the difference of the signal gradients and characteristic-curve correction factors for the gain being stored.

Abstract: A high-power electromagnetic source for HPEM pulses in a desired radiation direction includes at least three antennas fixed in relation to one another for pulse components, wherein at least two groups of antennas with a respective main direction are present, and a control unit for the activation and phase position of the pulse components for the superimposition for the HPEM pulse, wherein the current radiation direction of said pulse is selectable in an angle range around the main direction. A vehicle with an HPEM source has the antennas mounted in a fixed position or a support for the antennas is pivotably mounted on the vehicle. In a method for emitting the HPEM pulse, all antennas are controlled in order to select the radiation direction in the angle range of less than 360°.

Abstract: A munition module includes an ignition point of an explosive configuration positioned away from a detonator within a casing of the explosive configuration. In an initial state, an ignition channel runs from the detonator to the ignition point. The ignition channel is formed so as to be open in an initial state and self-sealing in an exploded state after a detonation has taken place. A warhead with the munition module contains an active covering which at least partially surrounds the explosive configuration and can be accelerated by the reacted explosive. In a munition having the warhead, the detonator is an impact detonator. A munition in the form of an air-burst munition contains the warhead.

The coupling unit couples the control surface drive to the control surface shaft in such a way that a movement of the control surface drive produces a rotation of the control surface shaft. To enable high forces to be applied reliably to a guided missile control surface, it is proposed that the coupling unit has at least one flexible tension element, which is secured on the control surface drive and is rolled up onto the control surface shaft to a certain extent.

Abstract: A method for operating a ground-based anti-aircraft system includes providing a group of main system components containing a sensor system, a tactical operation control and an effector system. Combat target sensor data are passed from the sensor system to the tactical operation control, processed therein and passed in processed form from the tactical operation control to the effector system, using the data to combat the target. A central integration module having a converter unit and a central data distributor allows differently constructed main system components to be connected. Data from all main system components are routed to the central data distributor by the converter unit and converted therein from component protocol into system-internal data protocol, and passed from the central data distributor to one or more main system components, through the converter unit, converting the distributed data back from system-internal data protocol into component protocol.

The optical system contains entrance optics and an optical link. The seek head further has a rolling-pitching system with a rolling frame and a pitching frame for aligning at least the entrance optics with the object. In order to be able to detect even objects that are far away and radiating weakly when the guided missile is rolling, it is proposed that the detector unit is arranged on the rolling frame for conjoint rolling.
