  • 摘要: 針對非高斯非均勻海雜波背景下雷達海面目標檢測性能改善的問題，該文基于海雜波的先驗知識提出了一種自適應(yīng)Rao雷達目標檢測方法。首先將海雜波的紋理分量和散斑協(xié)方差矩陣分別建模為逆高斯隨機變量和逆復(fù)Wishart分布的隨機矩陣，然后基于Rao檢驗和未知參數(shù)估計，設(shè)計了一種匹配海雜波特性的雷達目標自適應(yīng)Rao檢測方法。通過理論推導(dǎo)和實驗驗證了所提檢測方法對雜波平均功率和協(xié)方差均值矩陣具有恒虛警特性。仿真數(shù)據(jù)和實測數(shù)據(jù)實驗結(jié)果表明，在非高斯非均勻環(huán)境下所提檢測方法優(yōu)于已有檢測方法，并且具有良好的魯棒性。
    Abstract: An adaptive Rao detection method for radar targets is proposed based on the priori knowledge of sea clutter to improve the radar’s target detection performance in non-Gaussian and nonhomogeneous sea clutter. First, the texture component and the speckle covariance matrix of sea clutter are modeled as an inverse Gaussian random variable and an inverse complex Wishart random matrix, respectively. Then, an adaptive Rao detection method for radar targets, with quite similar characteristics as sea clutter, is designed based on the Rao test and unknown parameter estimation. The detection method is verified by theoretical derivation and experiments in demonstrating constant false alarm characteristics for the mean power and covariance mean matrix of sea clutter. The experimental results of the simulated and experimental data reveal that the proposed detection method outperforms existing detection methods in non-Gaussian and nonhomogeneous sea clutter environments with good robustness.
