为了解决单个天线覆盖范围和作用距离之间的矛盾,实现更广的空域覆盖和更高解码率的目标,采用多个通道进行S模式应答信号的接收、解码及融合纠错的方法,进行了两通道接收、解码及融合纠错实验,获得具有代表性的三批目标的解码数据。经过统计分析,结果表明多通道接收解码不仪可以覆盖更广的空域范围以增加数据量,同时在其中两个通道覆盖的交叠区域,采用信息融合纠错的方法可提供较好的相互纠错能力。
In order to find a solution to the contradiction between the coverage area of a single antenna and operating range of a single antenna, and to achieve the goal of the broader airspace coverage and higher decoding rate, the method for receiv- ing, decoding and integrated error correction of the mode S replies with multi-beam receivers is proposed. An experiment of receiving, decoding and integrated error correction is made by using of two-beam receiver , and three typical sets of decoded data are got. The paper makes a statistical analysis of these data, and the results show that method can not only cover broader airspace range to increase the amount of data, but also has a better integrated error correction capability in the area where two beams covered at the same time.
