Abstract :
Preamble detection, bit and confidence declaration are the most important part in signal processing of Mode S radar. If preamble detection or bit and confidence declaration algorithm do not perform well, it will affect error detection and correction. An effective algorithm to preamble detection, bit and confidence declaration based on 20MHZ sampling rate is proposed in this paper. Simulation results show that this algorithm is excellent in preamble detection, bit and confidence declaration.
