摘要

描述了模糊距离杂波对可实现杂波抑制的限制。杂波功率与距离的关系限制了可实现的杂波抑制。利用包含传播条件和雨杂波的模型,讨论了海杂波背景下的模糊距离效应。移动目标指示系统的局限性,说明了海杂波,其中传播受蒸发管道。填充脉冲对雨杂波和海杂波的好处已作了说明。

Clutter rejection limitations from ambiguous range clutter
Limitations on achievable clutter rejection due to ambiguous range clutter are described. The profile of clutter power versus range is shown to limit achievable clutter rejection. Ambiguous range effects are discussed in the context of sea clutter, using a model that includes propagation conditions, and rain clutter. Limitations in moving target indication systems are illustrated for sea clutter, where propagation is subject to evaporation ducts. Benefits of fill pulses are illustrated for rain and sea clutter.<>
