二次雷达C模式编解码实现

Encoding-Decoding Implementation for Mode C of SSR

针对二次雷达C模式高度编解码的实现过程,分析了查表法在高度编解码中的优缺点,归纳、总结并实现了公式法在二次雷达高度编解码中的运用。真实数据环境下对高度编解码的实验验证结果表明,公式法能在很大程度上达到空中交通管制对数据处理的时效性和准确性要求,在仿真设计中很好地克服了查表法建表繁锁、占用内存资源多等缺点,从而使得在软硬件实现上更加方便、快捷。

For the implementation process of the height encoding - decoding for mode C of secondary sur- veillance radar （SSR）,the advantages and the disadvantages of the look- up table（LUT） method in the height of encoding - decoding are analysed. The application of the formula method in height encoding - de- coding for SSR is summarized and implemented. The real data encoding - decoding under the environment of the height experimental validation shows that the formula method can largely meet the data processing re- quirements on timeliness and accuracy in the air traffic control（ATC） and in the simulation design,it can overcome such shortcomings of LUT method as cumbersome to build the table, heavy memory resources con- sumption ,which makes the software and hardware implementation more convenient and faster.
