改进的箔条干扰极化识别方法
Modified Polarization Recognition Method for Chaff Jamming
摘要
Abstract
With the development of chaff manufacture technology,it is possible to control the orienta-tion of chaff through weighting.The original chaff recognition method can’t recognize this type of chaff. Based on the orientation statistics model of the weighted chaff jamming,the polarization characteristics of the weighted chaff jamming are derived theoretically.It is pointed out that the original method is challenged by the weighted chaff jamming.A modified polarization recognition method is proposed according to the investi-gation.The performance of the original method and the modified method are compared through computer simulation.It is proved that the modified method is more adaptable than the original method.Especially for the vertical oriented chaff jamming,the original method can’t work.The modified method adapts well to all types of chaff and can recognize the chaff cloud correctly with high probability.关键词
