一种动中通地面跟踪系统的FPGA实现
FPGA Implementation of Surface Tracking System for a Satellite Communication on the Move Terminal
摘要
Abstract
To solve the problem that mobile satellite communication system may lose spacial targets in the tracking state and the search speed of mechanical scanning system is slow,a new mobile satellite communication system based on field programmable gate array (FPGA) is designed.The signal received by system antenna is sent to the digital signal processor through radio frequency (RF) processing,then the digital signal processor estimates target's orientation according to related information.The working state of the whole system which has a good man-computer interaction is controlled by the upper computer and system can quickly search or track after losing spacial target.The antenna array is driven by a direct current (DC) motor in the horizontal direction to achieve 360 degree azimuth scanning coverage and beam switching with different angles is used in the pitch direction.The system can locate the spacial target position according to energy criterion in a short time,and the operating efficiency of the satellite communication on the move terminal is improved.关键词
