摘要

提出了一种利用辐射式微带贴片天线元件减小给定目标在固定方向上的散射(即雷达横截面)的技术。该系统的设计是使贴片的辐射以雷达信号的载波频率抵消从指定方向上的物体反射的雷达信号，从而减少从指定方向上的物体散射的时变雷达信号，使入射时变雷达脉冲从已知方向到达。应用包括频谱共存和雷达的EMI降低。

Active Scattering Cancellation Using a Microstrip Antenna Element

A technique for reducing the scattering (i.e., radar cross section) of a given object in a fixed direction is presented, which makes use of a radiating microstrip patch antenna element. The system is designed so that the radiation from the patch cancels a radar signal reflected from the object in a specified direction at the carrier frequency of the radar signal, and therefore reduces the time-varying radar signal that is scattered from the object in the specified direction for an incident time-varying radar pulse that arrives from a known direction. Applications include spectral coexistence and EMI reduction from radars.
