摘　　要：干扰效果评估是评价和比较干扰方法优劣的重要方法。在分析正弦调频干扰与锯齿调频干扰的基础上,发现两种方法都能产生覆盖式和斑点噪声式干扰模式,这就对评估两种干扰方法的优劣带来了难度。本文利用两种具有针对性的评估方法分别对两种干扰模式进行评估,增加了评估结果的准确性。最后利用实验仿真对干扰效果进行了定量分析。Jamming effect evaluation is an important mernoo on jut^l~,s ~ c J methods. Based on analysis of sinusoidal frequency modulation and sawtooth frequency modulation jamming to SAR, it is obtained that the two methods can both produce mantle style and spot noise style jamming, which makes the jamming effect evaluation on the two jamming methods more difficult. Therefore two pertinent methods are adopted to make the evaluation more exact. The quantitative analysis of jamming effect evaluation is executed through the simulation.
