In this paper, the Power Band Graph (PBG) modeling method is used to realize modeling of the human circulation system and conduct a simulation study on a simplified physiological system model.
In the highly crowded HF band, available continuous bandwidth is very narrow, this threaten the viability of HF radar based on the continuous spectra signal system seriously.
在拥挤的高频频段，可用的连续带宽比较窄，基于连续谱信号体制的高频雷达的生存能力受到严重威胁。

In the spite of use of sequence image compression coding in most monitor system, such problem as the image quality degradation, Mosaic will appear in the narrow band.
