摘要
针对现代电子战日益复杂、密集的电磁环境下雷达信号的侦收分选面临着的严峻考验,提出分层分级把环境信号脉冲描述字数据流进行分类综合预处理的方法,稀释脉冲数据流以减轻后续信号分选的压力,介绍了基于信号的方位、频率、脉宽等参数预处理的流程,对已知信号预处理和未知信号预处理要点做了说明,并通过仿真验证了该方法的正确性和有效性。
In view of the increasingly complex electromagnetic environment in the modem battlefield, radar signal sorting is facing se- vere challenges, put forward the hierarchical classification the environment signal PDW dataflow synthetically pretreatment method to dilute the dataflow then reduce the stress of the follow-up signal sorting, briefly introduced the presorting of radar signal processing flow based on the orientation of signal, the frequency and pulse width parameter, and explains several main points of the known signal preprocessing and the unknown signal preprocessing, the correctness and effectiveness is validated by computer simulation.
