摘要
从自适应信号处理的角度出发 ,描述了阵列天线部分单元仅相位加权波瓣综合方法 ,并通过计算实例验证了该方法的正确性。该方法可用在天线波瓣图中设置宽凹口以对付宽带宽角干扰 ,亦可用于机载雷达天线不对称波瓣赋形以抑制地海杂波等。
Based on adaptive signal processing theory, this paper describes a pattern synthesis method, which only changes the phases of array part elements and is so called part phase only weighting method (PPWM). Its validity is verified by some computational examples. As an application, the method can set wide notch in the antenna pattern in order to reject jammers with wide bandwidth and from wide angle. In the AEWR antenna, it can be used to form an unsymmetrical shaping pattern for suppressing clutters from the earth and sea. In comparison with the full phase only weighting method for pattern synthesis, the part phase only weighting method for pattern synthesis is more realizable and more flexible.
