The homodyned-K (HK) distribution is a three-parameter density function used to study mixed-species radar and ultrasound scattering phenomena. We analyze the distribution that results from corrupting the HK with additive Gaussian noise (HKN). This modification enables analytic study of the HK in the presence of system thermal noise in radar and ultrasound systems. The moments of intensity of the HKN are derived and a new moment method parameter estimation algorithm is tested in simulation.

具有加性高斯噪声的零差 K 分布

零差 K (HK) 分布是一个三参数密度函数，用于研究混合物种雷达和超声散射现象。我们分析了用加性高斯噪声 (HKN) 破坏 HK 所导致的分布。这种修改能够在雷达和超声系统中存在系统热噪声的情况下对 HK 进行分析研究。推导出了HKN的强度矩，并在仿真中测试了一种新的矩法参数估计算法。
