天波超视距雷达海面非后向散射特性建模分析

运用微扰法推导了非后向散射下的天波超视距雷达海杂波模型，将此模型进行计算机仿真，并定性分析此模型下双基地角、雷达工作频率、风向、风速、入射角对海杂波回波强度的影响，为非后向散射下天波超视距雷达的目标检测和雷达布站提供了科学依据。

Analysis of Non-backscattering Characteristic Modeling for Sky-wave Over-the-horizon Radar on The Sea

This paper uses small perturbation method (SPM ) to deduce the sea clutter model of sky‐wave over‐the‐horizon radar (OT HR ) under the condition of non‐backscattering ,performs computer simulation to the model ,and analyzes the influence of bistatic angle ,radar operating fre‐quency ,wind direction ,wind speed ,incidence angle on the echo intensity of sea clutter based on the model ,which provides the science basis for target detection and radar distribution of sky‐wave OT HR under the condition of non‐backscattering .
