Polyphase Coded Radar Waveforms in Active Noise Jamming

The issues of radar resistance against active noise jamming and probability of correct range estimation in active noise jamming scenario had been very poorly published. In this paper we deal with these issues. The aim of this paper is the analysis of chosen polyphase codes and comparison of their performances in active noise jamming scenario from the correct range estimation point of view. On the basis of our findings, it is very useful to use polyphase codes for the radar signal detection in active noise jamming scenario and corresponding range estimation. Results of our experiment shown that the use of tested polyphase coded radar waveforms increased radar resistance against active noise jamming. When using Golomb code and P3 code we achieved the best results in our experiment.
