摘要： Provided are a directional pattern calculation method and apparatus for a beam pointing adjustable antenna. In the design method, key control factors are quantized, for example, a arrangement and combination modes for a plurality of slot units and wave-controlled codes for conducting and cut-off states of a slot unit, and different combinations of slot units and a far-field directional pattern of a controlled array antenna are evaluated, so that electrical performance indicators of the array antenna can be further evaluated. Weighting calculation is implemented for a directional pattern of a beam pointing adjustable antenna. Key information such as a form of a slot unit and a arrangement and combination modes for slot units can be globally optimized.

[Solving Means]
A radar apparatus includes multiple antennas, a power feeding circuit, and dummy antennas. The multiple antennas have a predetermined length in a first direction and are arranged in an array form in a second direction that intersects the first direction. The power feeding circuit is connected to the multiple antennas. The dummy antennas have a length different from the predetermined length and are arranged so as to sandwich the multiple antennas in the second direction.

摘要： A method for simulating electromagnetic interactions between an antenna with a reflecting front face and at least one electromagnetic radiator and an electrically large interaction structure placed in front of the antenna comprises providing an antenna model representing the antenna, the antenna model comprising an antenna surface representing the front face and at least one field source representing the at least one radiator, wherein the field source is placed at the antenna surface and is configured as a far field source that is defined by a predetermined radiation pattern, and wherein direct electromagnetic interaction between the field source and the antenna surface is avoided. The method further comprises determining electromagnetic radiation launched by the field source based on the predetermined radiation pattern, propagating the radiation using an asymptotic numerical method, and determining interactions of the radiation with the interaction structure and with the antenna surface.

摘要： A system for centralized reporting of alarm conditions in a multinode data handling system includes an alarm concentration unit at each node of the system for collecting alarm conditions. Each alarm concentration unit is coupled to a signal transmission unit which generates alarm messages and transmits the messages to a centralized node. The centralized node includes means for comparing each received messages with previously received messages stored in a memory and for amending the memory when the most recent received message differs from a previously stored message.
