摘　　要：天基预警雷达以卫星为载体,可以突破领空领海限制,实现视距外全天候全天时的动目标监测。文中以天基预警雷达空中目标区域搜索为应用场景,针对卫星高速运动导致的波束脚印移动问题,提出了一种可实时补偿卫星高速运动影响的扇区建立与波位编排方法,以最少的波位数确保了搜索区域的全覆盖,满足星上实时处理的工程实际需求。Space-based early warning radar uses satellites as the carrier,which can break through the territorial restrictions and achieve surveillance of moving targets regardless of the time and weather.This paper takes the aerial moving target indication as the application scenario,and proposes a sector division and beam position arrangement method,which can compensate the beam footprint movement caused by high-speed motion of satellite.As a result,this method can ensure the full coverage of search area with beam positions as least as possible,and meets the practical engineering needs of on-board real-time processing.
