摘要 PDW数据是对雷达脉冲的数字化描述,在复杂电磁环境仿真中,基于PDW数据构建雷达信号环境的应用越来越普遍。针对构建雷达信号环境的可变性需求,采用PDW数据多通道编批及同时到达信号处理,相同辐射源多参数比对与筛选,基于实际空间关系的雷达信号入射角度和幅度修正,以及PDW数据高速存储的方法,对PDW数据进行二次处理和实时存储。能够根据用户需求,任意定义PDW数据输出的频率范围,以高效率和低消耗的方式,实现雷达信号环境在空间和功率分布上的灵活变化,体现电磁环境在空域和能量域上复杂多变的特征。提出了使雷达信号环境具有可变性,并提出了PDW数据高速存储的实现方法。 The PDW data is a kind of digital description to radar pulse.In complex electromagnetic environment simulation field,constructing the radar signal environment by PDW data is more and more rife.For it’s requirement of variability,By using resetting PDW data batch numbers from multichannel and simultaneous signal processing,comparing multi-parameter of the same radar radiation source and selecting it,modifying the radar signal incident angle and amplitude base on the reality space relation,and the high-speed storage method for PDW,these can provide a secondary treatment and real-time storage to the PDW data.According to the user’s requirement,it can define the PDW data output frequency rang,realize flexible changing the space and time parameter distributions of the radar signal environment with high efficiency and low consumption,It reflects the complex and changeable characteristics of electromagnetic environment in airspace and energy field.
