摘要：

为掌握卫星导航接收机电磁辐射效应规律, 以某型导航接收机为试验对象, 采用全电平辐照法对其进行单频连续波和带外双频电磁辐射三阶互调阻塞效应试验, 通过试验验证了三阶互调阻塞效应模型的准确性。结果表明, 受试导航接收机对工作频率频偏-4~18 MHz范围内的单频电磁辐射较为敏感, 抗负频偏电磁干扰的能力远大于抗正频偏电磁干扰的能力; 带外双频三阶互调敏感场强显著低于相同频点的单频阻塞干扰场强, 最大差值可达46 dB; 负频偏端三阶互调阻塞干扰因子峰值与正频偏端峰值之比高达20余倍, 敏感频偏范围宽1倍以上。

Abstract:

In order to master the interference rule of satellite navigation receiver under electromagnetic radiation, a navigation receiver is taken as the experimental object, the full level irradiation method is used to carry out the electromagnetic radiation test of the single frequency continuous wave and the third-order intermodulation blocking effect test of the out-of-band dual-band electromagnetic radiation, the accuracy of the blocking effect model of third-order intermodulation is verified by experiments. The results show that the tested navigation receiver operating frequency in the range of -4~18 MHz offset is more sensitive to single-frequency electromagnetic radiation. The ability to resist electromagnetic interference in negative frequency offset is much greater than that in positive frequency offset. The field intensity of the third-order intermodulation on the dual-band is significantly lower than the single frequency blocking interference field at the same frequency point, and the maximum difference is up to 46 dB. The ratio of the peak value of the third-order intermodulation blocking interference factor at the negative frequency deviation end to the peak value of the positive frequency deviation end is up to more than 20 times, and the sensitive frequency deviation range is more than twice the width of that of the positive frequency deviation end.

Key words: navigation receiver, single frequency continuous wave, electromagnetic radiation, blocking effect, third-order intermodulation
