摘要
研究雷达干扰效能准确性评估问题,在对传统的基于雷达发现概率干扰效能评估模型进行改进,使改进模型更贴近干扰效能评估的实际需要。通过分析了雷达基本属性(含抗干扰属性)和干扰机基本属性(含频率瞄准属性)、目标性质和空间衰减对雷达发现概率的影响。提出压制性干扰效能评估方法,改进雷达发现概率的干扰效能评估模型,在改进模型中引入了频率瞄准因子和反对抗因子,对不同频率瞄准度下以及不同抗干扰措施下的干扰效能评估进行仿真。结果验证了改进模型的合理性和有效性。
An improved jamming effect evaluation model based on radar detecting probability is presented to meet the practical demand. Firstly, special attenuation effect and the impact of fundamental properties of radar including ECCM properties, jamming including frequency collimation properties and target on radar detecting probability are discussed. Secondly, oppressive jamming effect evaluation is analyzed. Then, an improved jamming effect evaluation model is proposed, in which the frequency aiming factor and ECCM factor are introduced, to solve the problem of jamming effect evaluation under different degrees of frequency aiming and ECCM. Computer simulation results prove the rationality and validity of the modified model.
