摘要: 针对车载中短波测向设备，提出了一种调幅广播信号的测向算法。与传统测向算法相比，该方法额外利用了调幅信号的非圆特性，构造出虚拟阵列孔径，可以有效提高测向精度。计算机仿真验证了所提方法的性能优势。
Abstract: A direction-finding algorithm for AM broadcasting signals is herein proposed for the application in vehicle-mounted mediumwave/shortwave direction-finding devices. Compared to the conventional algorithm, it has exploited the noncircularity property of AM signals, leading to the concatenation of virtual array aperture and enhanced direction-finding accuracy. Computer simulations have demonstrated the efficacy of the proposed algorithm.
