摘　　要：利用脉间跳频、频率捷变信号的脉间频率不同等特性,提出了一种对脉间跳频、频率捷变信号的双通道高精度测向算法。该算法相对于传统的多基线干涉仪测向系统,大大减少了设备的成本,仅仅通过2个通道便可完成高精度测向。Using the characteristic that the intra-pulse frequencies of intra-pulse frequency hopping and frequency-agile signals are different, this paper puts forward a dual channel high accuracy di-rection-finding algorithm for intra-pulse frequency hopping and frequency-agile signals. Relative to traditional multi-baseline interferometer direction-finding system, this algorithm greatly reduces the device cost, and completes the high accuracy direction-finding through only two channels.
