电离层斜向返回探测系统中的DSP设计
The Real-Time DSP System Design of the Ionospheric Oblique Backscattering Sounding System
【摘要】 研制了一个应用于电离层斜向返回探测的实时同步信号处理系统 该系统采用间隔收发体制 ,无探测盲区 ,比STUDIO系统探测精度更高、速度更快、距离更远 ,并且软件化程度更高 ,适应性更强
【Abstract】 s: Develop a real\|time synchronous DSP scheme which is used in the Ionospheric Oblique Backscattering Sounding System(IOBSS).IOBSS adopts discontinous wave mechanism and has no blind area.It runs well in experience.Compared with the STUDIO system,IOBSS has better precision,higher speed and greater sounding distance.And more,IOBSS has adopted more software components which make it much more adaptable.
