| 摘 要： | 星载数字调零天线对应的干扰信号主要是人为大功率阻塞式干扰。针对该情况，提出调零状态保持策略和干扰源信息存储策略。调零状态保持策略可以有效防止闪烁式干扰源对调零天线造成的潜在威胁，避免调零天线被动频繁调零对系统稳定性的影响。干扰源信息存储策略可以得到具有针对性的调零状态保持时间，避免盲目设定调零状态保持时间导致无法适应各种干扰策略的情况，从而使调零天线具有更强的自适应性。

| Abstract: | The main jamming against digital nulling antenna on satellites is hostile high-power blocking interference.Aiming at the situation,this paper proposes nulling state maintain and interfering resource information store strategy.Nulling state maintain strategy can prevent the nulling antenna from the potential threat of blinking-jamming,avoid the impact of nulling antenna passive frequent nulling for system stability.The interfering resource information store strategy can get nulling state maintain time with pertinence,avoid the situation of blindly setting nulling state maintain time which can not adapt to all kinds of interfering strategy,and it makes nulling antenna has stronger adaptability. |
