摘要: The invention relates to an antenna in stripline technology, in which the dipoles and the feeder network are etched in one single process. The connections of the dipoles are realized as two-wire transmission lines, fed by Schiffman couplers. The polarization of the antenna is selectably chosen by twisting the transmission lines.

摘要: A low cost and rugged apparatus for assessing damage to a ship's hull. Parallel optical fibers run along the ship's hull. If damage occurs, the fibers are broken and the breaks are detected by a centrally located unit. The location and extent of damage can be accurately determined. The fibers can also be used to detect fires and to convey operator induced alarm signals.

摘要: Radar apparatus provided with a transmitting unit (1), having a transmit phase shifter for providing each transmitted pulse in a burst with a selected phase shift, and a receiving unit (7), having a receive phase shifter (9) for cancelling the selected phase shift upon reception. This enables unimpeded radar transmissions and causes an operational repeater jammer to be misled.

摘要: The invention relates to an arrangement and a method for suppressing spurious targets, particularly those caused by birds, in an infrared search device. Potential targets that show comparatively strong fluctuations are qualified as spurious targets. Only targets moving against a homogeneous background are subjected to an evaluation.

摘要: A radar apparatus that is provided with auxiliary antennas (5, 10) of an omnidirectional nature. In addition to customary ECCM applications, such as side-lobe suppression and side-lobe blanking, the auxiliary antennas (5, 10) are also used for the emission of frequency-shifted pulses which are emitted simultaneously with radar transmitter pulses. To this effect, the radar apparatus is provided with auxiliary transmitters (8, 13). Furthermore, auxiliary receivers (6, 11) have been provided for analyzing the responses of jammers to the frequency-shifted pulses.

摘要: A radar apparatus provided with transmitter means (1), rotating antenna means (2) and receiver means (3) for the transmission per burst and the processing in a video processor of radar echo signals. The video processor includes moving target detection unit (4) provided with a doppler filter bank, for instance an FFT processor, and slow moving target detection unit (6), provided with coherent clutter maps, one map for each radar transmitter frequency used. The coherent clutter maps are also used for reducing the clutter strength of radar echo signals which are applied to the moving target detection unit (4), by subtracting the coherent clutter strengths stored in the clutter maps from the radar echo signals.

摘要: A search radar system, is provided which includes at least one search radar device (1) having a primary antenna (2) and at least one secondary radar device (3) having an SSR/IFF antenna (4). The radar devices (1, 3) independently supply plot data from which signals are derived that are each suitable for presentation on a radar display. The antennas (2, 4) are oriented in opposite directions so that the said signals are derived from individual plot data representing successive detections by the respective antennas of the same target which can be individually presented. Hence, the data rate of the radar system is doubled relative to a conventional radar system having a conventional secondary radar device and a conventional antenna system.
