雷达脉冲上升/下降沿测量影响因素分析模型

为实现对雷达脉冲上升/下降沿的准确测量，在对其影响因素分析的基础上，将Logi stic回归分析方法引入雷达脉冲上升/下降沿测量的影响因素分析，提出了雷达脉冲上升/下 降沿测量的影响因素分析模型。采用因子分析和多元相关回归分析法对各影响因素的作用和 模型的回归显著性进行了分析。实验结果表明，多径效应的影响最大，其次为通频带宽，影 响最小的是杂波效应。同时，结果分析表明提出的影响因素分析模型是合理的，这对高精度 的雷达脉冲测量以及影响程度评价具有一定的参考价值。

Factors Analysis Model for Radar Pulse Rising/Falling Edge Measurement

To accurately measure radar pulse rising/fall ing edge, the Logistic regression analysis method is introduced into the influe nce factors analysis of radar pulse rising/falling edge measuring based on the a nalysis of its various factors, and the influence factors analysis model for the radar pulse rising/falling edge measurement is proposed. The role of various i nfluences factors and the regression significant characteristics of the model ar e analysed by using factor analysis and multiple correlation regression analysis . Experimental results show that the greatest impact on the measurement result is the multipath effect, followed by passband width. Minimal impact on the measu rement result is the clutter effect. Meanwhile, the results also show that the proposed analysis model of influence factors is reasonable and it has certain re fer ence value for the precision measurement and the impact evaluation of radar puls es.
