摘要
在电子侦察的信号处理中,脉冲宽度具有重要的意义,因此在脉冲宽度的测量和参数分析上需要进行精心设计。即使如此,在实际环境中,受各种客观因素的影响,脉冲宽度的测量值将出现各种离散的分布,不仅很难作为信号分选的依据,也将影响脉冲宽度的参数分析结果,并对后续的信号相关识别带来重大的影响。本文分析了工程应用中脉冲宽度测量和参数估计的实际情况,并提出了处理的方法。
Since pulse width （PW） plays a very important role in signal processing of electronic reconnaissance, delicate design on measurement of PW is required. Even so, in the real environment with influence of various objective factors, the measurement value of PW will have different kinds of discrete distribution. Therefore it is very difficult to take PW as good basis for signal sorting, and it will affect the parameter analysis rest.tit. Moreover, it will considerably affect the subsequent signal correlation identification. The article analyzes the above-mentioned actual situation and brings forward the corresponding processing methods.
