摘　　要：提出了一种基于接收天线方向图和辐射源信号幅度、方位的最大幅度测向算法。新算法通过建立测向包络数学模型,利用辐射源信号幅度和方位动态估计模型参数,计算包络曲线最大值对应变量值获取辐射源方位。仿真实验结果表明新算法与传统算法相比,具有测向精度高、运算量低、适应复杂体制辐射源信号能力强的特点。A direction- finding method is proposed based on the radio signal＇s amplitude and the direction of arrival and the radiation pattern of the receiving antenna. Building the mathematic model of direction finding envelop,estimating model parameter by the amplitude and the direction of the radiant signal,calculating the park of the conic,the direction of radiant is obtained. Experimental results show that the new algorithm has the high- precision and low computing adaptable advantage.
