PHASED ARRAY PLANAR ANTENNA FOR TRACKING A MOVING TARGET AND TRACKING METHOD

摘要

In order to track a target moving relative to the platform in phase array antenna housed in the de-platform system The antenna system includes a first planar active subsystem to operate as any linear polarization direction of the RF signal receiving / transmitting and optionally perform electronic scanning; Coupled to the active subsystem is operative in a first rotational movement of the active subsystem with respect to a first axis perpendicular to the plane defined by the planar active subsystem 2, subsystem roll; Second, a third elevation roll subsystem coupled to the subsystems of the fourth azimuth subsystem, subsystem azimuth defines the central axis of the antenna system operates to provide the rotational movement of the first planar subsystem with respect to the central axis , elevation subsystem includes a plane and azimuth plane which will provide the angle between the direction defined by the configured sub-system, the third elevation subsystem defined by the active subsystem, thereby, the linear polarization direction of the allowing the target to be substantially aligned with respect to the linear polarization direction of the received and / or transmitted RF emission by the target location to determine a first planar active subsystem.
