论文摘要
使用LPA LPI射电望远镜进行5年监测脉冲星的搜索是在覆盖每日17,000平方度的96个空间梁中进行的。检测到五个新的脉冲星。在求和功率谱中选择了进入脉冲星的候选者。允许使用噪声发生器来重新归一化数据并正确地求和，以对天空中各个方向的功率谱进行正确求和。因此，与单个观察结果相比，灵敏度提高了20倍以上。对于脉冲持续时间大于100 ms的脉冲星，在降低时 +30o <dec < +40o等于1.2 mjy和0.4 mjy in/in in/out in Galaxy平面。
The search of pulsars in monitoring observations being carried out for 5 years using LPA LPI radio telescope was done in 96 spatial beams covering daily 17,000 square degrees. Five new pulsars were detected. Candidates into pulsars were selected in the summed power spectra. The use of a noise generator allowed to renormalize the data and to perform correct summing up of the power spectra for individual directions in the sky. Herewith, the sensitivity increased more than 20 times in comparison with individual sessions of observations. For pulsars with pulse durations greater than 100 ms at declinations +30o<dec.<+40o it is equal to 1.2 mJy and 0.4 mJy in/out of the Galaxy plane.
