摘要
讨论了机-机双基地雷达空间同步,介绍了DBF同时多波束空间同步法,推导了接收波束方位角和俯仰角公式。分析了采用DBF技术的脉冲追赶空间同步法的基本原理,介绍了实现脉冲追赶的两个重要参数,接收波束宽度和波束扫描速率,并给出空间同步方案。
Synchronization problem is one of the key technologies in bistatic radar on airborne plat. Spatial synchronization is discussed in this paper. The method of simultaneity multi-beam is introduced. The azimuth and elevation formulas of receiving beam are presented. The basic principle of pulse chasing adopted DBF is analyzed. Two important parameters, the width and scanning velocity of receiving beam are introduced. Synchronization scheme is also provided.
