摘要
多假目标干扰对雷达检测性能的影响是电子战研究的难点问题。对分布式多假目标干扰下组网雷达检测性能进行了分析,首先提出了对组网雷达的分布式多假目标干扰原理,然后研究了多假目标干扰对雷达网恒虚警率(CFAR)处理的影响,最后根据Albersheim的经验公式建立了一个适用于非起伏目标的雷达网检测概率计算模型,并且定义了干扰压制比作为衡量雷达网综合检测性能的评估指标。仿真结果验证了模型和方法的有效性。
To evaluate the radar detection performance in the jamming of multi-false target is a difficult problem in radar EW researches. The detection performance of netted radar system in the distributed jamming of multi-false target is studied. Firstly the distributed jamming theory of multi-false target is presented. Then, the constant false alarm rate （CFAR） performance of netted radar in the jamming of multifalse target is studied. Lastly, based on Albersheim＇ s experience formula, a new netted radar detection performance model with high precision is established, and a new method of evaluating the radar detection performance is presented. Simulation results verify the validity of the model and method.
