Abstract: A method of irradiating an electromagnetic pulse includes specifying a position of a target having electronic equipment; setting the light-condensing point based on the position of the target; and condensing the laser beam to generate plasma in the light-condensing point such that the electromagnetic pulse generated from the plasma is irradiated to the electronic equipment. In this way, a method and system for irradiating an electromagnetic pulse are realized which can irradiate the electromagnetic pulse of a large output while restraining diffusion of the electromagnetic pulse.

Abstract: A laser array device includes a first lens tube (10) through which a first laser beam (1) passes, a second lens tube (20) through which a second laser beam (2) passes, a support mechanism (72, 74) disposed to support the first lens tube (10) and the second lens tube to be parallel to each other, a first lens (12) arranged in the first lens tube (10), and a second lens (22) arranged in the second lens tube (20). A first temperature-rise suppressing mechanism (110) is disposed in the first lens tube (10) to suppress temperature rise of the first lens tube (10).

Abstract: An observation supporting apparatus includes a position specifying section which specifies a coordinate point of a moving object detected in a viewing field through once observation. An orbit estimating section calculates an estimate orbit of the moving object in the viewing field based on the specified coordinate points. Data necessary to estimate the position of the moving object out of the viewing field is acquired using the estimate orbit by the orbit estimating section.

Abstract: A brightness time change of the target object is analyzed and a periodic brightness change is extracted. By the matching with a database which includes data of a candidate of the target object, the features of the target object are estimated. If even the brightness data can be acquired even if the resolution of the optical observation is low, the features and states of the target object can be estimated.
