| Abstract: | This paper firstly sketchs the characteristic of Mode S responding signal processing, mainly including Mode S responding signal format and preamble detection arithmetic, confidence determinant arithmetic, and error detection and correction arithmetic. Then, the preamble detection arithmetic is especially introduced in detail, including video frequency processing, edge distilling, preamble detection, reference power computing, overlap testing, power coherence testing, DF verification and retouch, and so on. ... |
