| 摘 要： | 为了测量频率步进脉冲信号的功率值，需要将已有的脉冲测量技术加以改进.以频谱仪为测量工具，分别采用谱线法和包络法测量信号功率，为避免使用脉冲退敏因子，提出了一种更为快捷的测量方法.不同测量方法下的最大误差仅为1.08 dB.测量结果表明，新方法能以较快的速度在大的带宽范围内获得准确的脉冲信号功率值.

| Abstract: | In order to measure the power of the stepped-frequency pulse signal, the existing pulse measurement techniques need to be improved. Using the spectrum analyzer as a measurement tool, the power of the signal is measured by the spectral line method and the envelope method respectively. To avoid the use of pulse desensitization factor, a more rapid measurement method is proposed. The maximum error under different methods is only 1.08 dB. The power measurement results show that the new method can rapidly get the accurate pulse power value in a large bandwidth range. |
