The invention discloses a positioning method for an ADS-B (Automatic Dependent Surveillance-Broadcast) aviation system, and particularly relates to the technical field of ADS-B digital information transmission, and the positioning operation method specifically comprises the following steps: firstly, an ADS-B aviation aircraft outputs information in the position, height, speed, course and identification number of the aircraft from an information transmission channel by utilizing a GPS (Global Positioning System) technology; the audio signals are sent to transceiver equipment according to the broadcasted audio signals; compared with a traditional positioning method for an ADS-B aviation system, the fast ICA algorithm is adopted, the functions that the processor operates the fast ICA algorithm, noise interference information is removed, and ADS-B emission source signals are extracted are achieved, the noise interference signals are removed for the first time in the information transmission process, the accuracy of signal transmission is improved, the Kalman filtering algorithm is adopted, and the positioning accuracy of the ADS-B aviation system is improved. Filtering processing of the monitoring module is achieved, and the image sharpening function is improved.

    本发明公开了一种用于ADS‑B航空系统的定位方法,具体涉及ADS‑B数字信息传输技术领域,其定位运行方法具体包括下列步骤:首先ADS‑B航空飞机利用GPS技术,从信息传输通道输出飞机位置、高度、速度、航向及识别号中的信息,按照广播的声频信号发送至收发机设备;本发明与传统的用于ADS‑B航空系统的定位方法相比,采用了fastICA算法,实现了处理器运算fastICA算法,去除噪声干扰信息,提取ADS‑B发射出源信号的功能,达到了在信息传输过程中初次去除噪声干扰信号,提高传输信号的精确性,采用了卡尔曼滤波算法,实现了监控模块滤波处理,提高图像清晰化功能。
