摘　　要：在用修正的双谱法检测ＡＭ信号的基础上提出了一种新的解决方法——１．５维谱法，并且在一定条件下，提出了修正的１．５维谱方法，这些方法既能很好地检测ＡＭ信号，又具有计算量小、运算速度快的优点。Based on the modified bispectrum method to detect AM(amplitude modulation) signals, a new 1.5 dimension spectrum approach is presented. Furthermore,under a limited condition, a modified 1.5 dimension spectrum approach is also presented. Compared with the old method, these approaches not only can detect AM well, but also are much simpler and costs little computer time.
