The relationships of the infracallosal segment of the PerA to the CMA and the A2 segment of the PerA to the frontopolar artery were examined. The distance between the nasion and the site at which a parallel line directed along the long axis of the infracallosal PerA just proximal to the origin of the CMA artery crosses the forehead (which we have named the PC point) was also measured. In addition, the surgical approaches to DACAA were examined in stepwise dissections.

After rigorously mathematical deduction, some valuable conclusions are drawn: at the multiple times of symbol period, discrete peaks of the PACA function appear with 3 peaks in group, which includes a larger peak located in the middle and the other smaller two located symmetricly beside the larger one. The distance between small peaks is modulation offset of pulse position PPM.
经过严格数学推导,指出了TH-UWB信号的PACA函数不但在字符周期整数倍处出现离散峰值,而且按三个峰值(一大峰值左右对称出现小峰值)成对出现,大峰和小峰的间隔就是PPM调制时间偏移。
