有源对消技术是利用相干波的干涉效应，改变目标的散射分布，以减小在雷达方向的散射功率密度的一种有源隐身技术。本文通过理论分析和实验对其进行了原理性研究。实验中，采用有源对消技术使目标的雷达散射截面积缩减了１９．２ｄＢ。
Active cancellation technology is an active stealth technology that uses the interference effect of the coherent wave and changes the scattering distribution of the target to reduce the scattered power density in the radar direction. In this paper, theoretical analysis and experiments on the principle of its research. Experiment, the use of active cancellation of the target radar cross-sectional area reduced by 19.2dB.
