A wireless communication system including a shield room forming section, leaky transmission line, first antenna, first device, second antenna and second device. The shield room forming section covers an internal space with an electromagnetic wave reflector that blocks wireless communication. The leaky transmission line is provided with first and second leakage parts arranged inside the shield room forming section. The first antenna is arranged inside the shield room forming section and configured to be wirelessly communicable with the first leakage part. The first device is arranged inside the shield room forming section and has the first antenna. The second antenna is arranged inside the shield room forming section and configured to be wirelessly communicable with the second leakage part. The second device is arranged inside the shield room forming section and has the second antenna. The first device and the second device perform direct two-way wireless communication with each-other.

Wireless communication system using a leaky transmission line for direct two-way communication and usable in a flying object

The present invention is provided with: an antennahaving an antenna surfacefor radiating radio waves so as to have a prescribed plane of polarization; a second rotary mechanismwhich is connected to the antennaand which rotates the antennaabout a second rotation axis Ithat is set in a normal direction orthogonal to the antenna surface; and a first rotary mechanismwhich is connected to the second rotary mechanismand which rotates the antennaand the second rotary mechanismabout a first rotation axis Ithat is set in a direction slanted with respect to the second rotation axis I

Radar device and aircraft

A region extraction apparatus provided with a candidate extraction unit, a categorization unit and a region extraction unit. The candidate extraction unit extracts a difference region where a first ground surface image photographed from above at a first time point and a second ground surface image photographed at a second time point are different. The categorization unit estimates a first category of a first object photographed in correspondence with a position in the first ground surface image, calculates a first categorization image indicating a relationship between the position of the first object and the first category, estimates a second category of a second object photographed in correspondence with a position in the second ground surface image and calculates a second categorization image indicating a relationship between the position of the second object and the second category. The region extraction unit extracts an extraction region from the difference region.

Region extraction apparatus and region extraction method

A ranging apparatus transmits an optical input signal to an optical signal input/output unit mounted on a measurement target. The optical signal input/output unit receives the optical signal and transmits an optical output signal applied with an optical change, to the ranging apparatus. The ranging apparatus receives the optical output signal, measures a propagation distance from a light source a the light receiving unit through the optical signal input/output unit, and measures a relative position of the optical signal input/output unit based on the propagation distance. Thus, a distributed aperture radar is realized from the ranging apparatus and the optical signal input/output unit.

Measurement system and measuring method

A radar system contains a plurality of sub-modules which irradiate beams for a distributed aperture radar. Each of the plurality of sub-modules irradiates the beam, moves and, and communicates with an external unit for a distributed aperture process. The radar system may contain a command unit configured to command the sub-modules. The command unit measures each sub-module and communicates with the sub-module, acquires necessary data of measurement data of the sub-module, position data received from the sub-module, operation situation data of the sub-module and topographical data around the sub-module, calculates a synthetic beam pattern, calculates the arrangement of the sub-modules when the synthetic beam pattern becomes equal to a predetermined pattern, and instructs each sub-module to move based on the calculated arrangement of the sub-modules.
