摘　　要：讨论了二元频谱干涉的测距方法,分析了二元频谱干涉测距方法的统计误差,通过对比得出了二元频谱干涉测距方法的测量精度高于一元频谱干涉测距方法测量精度的结论,为频谱干涉类无线电定位,无线电测距及激光测距等精密仪器的方案设计提供了一定的理论依据。The range finding method of binary frequency spectrum interference is discused, and analyzes the statistical error margin of this method is analysed in detail. By contrast the conclusion that the precision of this method is superior to the single variable frequency spectrum interference measurement is made, which can provide theoretical basis for the tentative design of precision instruments such as the radar fix, radio distance-measuring and laser ranging etc in series of frequency spectrum interference.
