چکیده
|
Polyphase is a common class of pulse compression waveforms in the radar systems. oppermann code is one of the used codes with polyphone pattern. after compression, this code has little tolerant against doppler shift in addition to its high side lobe level. this indicates that the use of oppermann code is an unsuitable scheme to radars applications. this paper shows that the use of amplitude weighting functions improves properties of code and makes it an appropriate technique. noticeable reduction in sidelobe and false alarm as well as the increase of the target detection ability and doppler tolerant are the signature of amplitude weighting functions investigated and simulated in this study
