摘　　要：本文针对4型航空常用的数字信号处理(DSP)进行了大气中子单粒子效应试验,对辐照条件、试验环境、试验件安装及监测方法进行研究,并对试验结果进行了数据处理及分析。试验结果表明,该4型DSP在14Me V中子辐射下均发生了单粒子翻转(SEU是单粒子效应中的一种模式),TMS320C6416TBGLZA8、TMS320C6418ZTSA500、TMS320F2812及SM32C6415EGLZ50SEP的单粒子翻转截面分别为1.91e-7cm2/device、6.62e-7cm2/device、8.82e-9cm2/device及1.62e-7cm2/device,在12000m处的飞行高度下,器件发生的单位翻转率分别为1.15e-03n/(device·h)、3.97e-03n/(device·h)、5.29e-05n/(device·h)、及9.69e-04n/(device·h)。In this paper, the testing method of Single Event Effects （SEE） experiment to 4 types of commonly uesd DSP was studied, including the radiation condition, experiment environment, equipment install and monitoring methods, etc. The database of the experiment was also data processed and analyzed. The experiment result is that TMS320C6416TBGLZA8 DSP SEU cross-section is 1.91e-7cm^2/device, at 12000m altitude, SEU rate is 1.15e- 03n/device-h; TMS320C6418ZTSAS00 DSP SEU cross-section is 6.62e-7cm^2/device, at 12000m altitude, SEU rate is 3.97e-03n/（device.h） ; TMS320F2812 DSP SEU cross-section is 8.82e-9cm^2/device, at 12000m altitude , SEU rate is 5.29e-05n/（device. h） ; SM32C6415EGLZ50SEP DSP SEU cross-section is 1.62e-7cm^2/device, at 12000m altitude, SEU rate is 09.69e-4n/（device. h）.
