Real-Time data and confidence declaration algorithm for MSSR Reply

This paper presents a kind of method which can extract reply of Mono-pulse Secondary Surveillance Radar (MSSR) effectively at high density reply and introduce the real-time algorithm of confidence analyzing on the reply code. This arithmetic can not only extract code and confidence of the pulse reply code a time, but also fulfill the OVERLAP and de-FTUTI processing. The reply differentiation and confidence estimation can be correctly confirmed when there is multi-target reply-blend, providing available report form of the target trace.
