摘　　要：单通道单脉冲跟踪体制具有节省通道、可靠性高、成本低等优点,因此在卫星、遥感、气象等接收系统中得到广泛应用。它只用一个接收通道,简化了角误差检测系统,但增加了方位与俯仰的交叉耦合。本文结合工程实践,对遥测系统中常用的自跟踪体制的交叉耦合产生机理进行了分析,并给出工程应用中减少交叉耦合的几点建议。The single channel monopulse tracking system has some strong points such as saving channel,high reliability and low cost.It has been applied widely in the auto-tracking receiving system of satellites,remote sensing and weather.It needs only one receiving channel and simplifies angular error detecting system.However,it will bring the increase of crosscoupling of azimuth and elevation.Based on engineering practice,this paper analyzes the generating mechanism of crosscoupling of auto-tracking system often used in the telemetry system,and makes some suggestions of reducing crosscoupling.
