摘要
在电离层探测中 ,伪随机噪声编码探测仪与常见的线性调频电离层探测仪相比具有一定的优势。随着软硬件技术的发展 ,按照伪随机编码体制特点 ,将软件与硬件有机结合 ,可以形成具有良好开放性和灵活性的电离层探测仪。该文在介绍伪随机噪声编码电离层斜向返回探测仪原理和系统结构的基础上 ,使用面向对象的程序设计方法和可视化的开发工具 ,基于消息 /标志交换机制和软件生成时序的思想设计并实现了系统软件。
The pseudo-random noise(PRN) coded ionosonde has some advantages over linear frequency modulation(LFM) coded ionosonde in ionospheric sounding. Due to the development of software and hardware, an open and flexible ionosonde can be produced by combining the software and hardware according to the system′s characteristics. After introducing the principle and structure of the PRN oblique backscatter ionosonde system (OBIS), this paper presents the design and application of it′s system software based on mechanism of message/flag and the idea of software sequence by using object-oriented programming language and visualization toolkit.The program has open and flexible structure which makes the multimode ionospheric oblique backscattering sounding based on software become possible.
