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。
The satellite interfering signal corresponding to the digital zeroing antenna is mainly man-made high-power blocking interference. In view of this situation, the zero-state holding strategy and the interference source information storage strategy are proposed. The zero state keeping strategy can effectively prevent the potential threat caused by the flickering interference source to the zeroing antenna and avoid the influence of the frequent zeroing of the zeroing antenna on the system stability. Interference source information storage strategy can obtain the targeted zero-state holding time, and avoid blindly setting the zero-state holding time to be unable to adapt to various interference strategies, so as to make the zeroing antenna more self-adaptive.
