摘要
由于工作在高频段,高频地波超视距雷达的角分辨力较差,尤其是当阵长受限时。本文从实际出发,提出了一种利用最小方差信号无畸变响应(MVDR)波束形成实现超分辨的方法,单目标实测数据及部分仿真目标数据的处理结果表明了其有效性。
Owing to the decametric wavelength, the angular resolution of High Frequency Surface Wave OTH Radar (HF SWOTHR) is usually coarse especially when dimensions of antenna array are restricted. An actual implementation of Minimum Variance Distortionless signal Response (MVDR) beam -former to accomplish super resolution is proposed in this paper. Results from the experimental data of one target and simulated data of two targets demonstrate its reasonableness and validity.
