摘　　要：基于常规波束合成的分裂阵互谱测向算法是目前广泛应用的被动阵列精确测向技术。目前,常规的分裂阵互谱定向算法在实际的水下阵列布阵形式下可探测的频率范围较小,不能满足实际需求,在工程应用的角度,算法结构还有改进的空间。通过理论分析和仿真,在原有理论框架的基础上,改进了算法的流程和结构,形成了2种改进的定向算法。仿真结果表明,改进算法的精度高于阵元直接相关法,证明了改进算法的有效性,为实际工程应用提供了新的思路和理论参考。Cross-spectrum direction-finding with splitting beam based on conventional beam-forming（ CBF） is a widely used algorithm in accurate passive direction-finding. The existing conventional algorithm has a narrow processing band of frequency,which can＇ t be used in practical engineering. A research has been conducted to propose modified algorithms through theoretical analysis and simulation based on the conventional algorithm. The two modified algorithms provide new direction and theoretical reference for practical application of engineering.
