【摘要】 水面水下目标分辨是水声探测目前亟需解决的难题之一。匹配场方法将水声传播机理应用于阵列信号处理中,可以在浅海环境下实现水面水下目标深度分辨。仿真分析单垂直阵对相同距离、方位角处不同深度的两目标的分辨能力,结果显示其分辨率接近理论分辨率,验证了理论的正确性与可行性。更多还原

【Abstract】 Target depth resolution is a difficult and urgent problem for underwater acoustic detection.Incorporated the propagation physics directly into the array processing,matched field method can distinguish two targets at diffirent depth while have same distance and azimuth in shallow sea environment.The theoretical value of matched field depth resolution is about L_z =（2π）/(2K_zM)（Z）.Single vertical array MFP simulation has been done for target depth resolution,the results showed that the resolution is basically corresponds theoretical value.更多还原
