摘要: 高频外辐射源雷达是典型的双基地雷达，双基地海杂波建模及仿真对于该雷达具有重要的研究价值。该文首先建立了双基地高频雷达一阶海杂波时域信号模型，并给出了详细推导过程。然后根据已建立的信号模型，提出一种采用带通滤波和希尔伯特变换仿真一阶海杂波的新方法。仿真结果验证了该信号模型及其仿真方法的有效性。

Abstract: High Frequency (HF) passive radar is a typical bistatic radar, and the modeling and simulation of sea clutter in bistatic radar are worth researching for HF passive radar. The paper first establishes a time-domain signal model of the first-order sea clutter in bistatic radar with a detailed derivation process. Then, based on the signal model, a new simulation method for the first-order sea clutter using band-pass filter and Hilbert transform is proposed. Simulation result verifies the validity of the proposed signal model and simulation method.
