    摘要： An apparatus for converting frequency which is used as a converter which, for example, converts a microwave signal received from a satellite broadcast into a signal of a lower frequency, comprises a circular waveguide (12) into which a signal is supplied, a rectangularwaveguide (14) which is provided at its final end with a rectangular waveguide-to- microstrip line converter (15), and a circular-to-rectangular waveguide converter (13) connecting between the circular waveguide (12) and the rectangular waveguide (14). The diameter of the circular waveguide (12) is set so that the cut-off frequency of the circular waveguide (12) is lower than the frequency of the received signal and higherthan a local oscillation frequency, sothatthe circular waveguide (12) can act as a high-pass filter, to satisfy noise factor characteristics and increase the image-noise ratio, as well as reduce leakage of the local oscillation signal.

    摘要： A method for controlling an antenna of a mobile communication application system based on double quaternions in MEMS inertial navigation. The method comprises: introducing an antenna control quaternion based on a navigation attitude quaternion; in each interrupt cycle of a navigation computer, updating the two quaternions respectively using a carrier system measured by a gyroscope relative to a rotation vector of an ideal platform coordinate system; in each filter cycle, correcting the error of the navigation attitude quaternion respectively using a Kalman filter; according to the relationship between the attitudes determined by the two attitude quaternions, determining the angular speed in an antenna control instruction; and finally, driving a servo system to rotate at an antenna servo control angle converted by an antenna control quaternion attitude. A system for controlling an antenna of a mobile communication application system based on double quaternions in MEMS inertial navigation can achieve the accurate control of the directivity of an antenna of a mobile communication application system using the control method as a control flow. The present invention can effectively prevent the servo system of the antenna of the mobile communication application system from being impacted by the instable navigation attitude quaternion in the transient process of the Kalman filter, thereby effectively shortening the satellite aiming time of the mobile communication application system.
