摘要:
A system for target designation by laser comprises circuitry for precise alignment of the aircraft and pod lines of sight. The alignment circuitry operates digitally in a computer in which the director cosine data of the aircraft and pod lines of sight are compared to provide error signals fed to corresponding servo-controls. Alignment is obtained by the introduction of corrective data utilized for producing vector rotations, the corrective data being produced by means of a manually controlled stick device, integration circuits and a non-volatile memory.

Method and device for determining the air turbulence likely to be encountered by an aircraft. The device (1) which is provided on a second aircraft comprises a means (12) for using a turbulence indication from a first aircraft to make a prediction of the impact of the turbulence on this second aircraft if it is located in a particular position, and a means (13, 14) for using this prediction.

摘要:
A broadband array antenna which delivers an axisymmetric main lobe. The antenna includes patches arranged with an interruption of periodicity in one of the planes and is corner-fed by tree like feed lines from a central point of energization. Opposite each path is a parasitic element for broadening the band. This device can be used in particular with measurement radar.
