In radar sensor network (RSN), interference with each radar can be effectively reduced when waveforms are properly designed. In this paper, we firstly perform some theoretical studies on co-existence of phase coded waveforms in RSN. Then we give the definition of a new set of triphase coded waveforms called optimized punctured Zero Correlation Zone sequence-pair set (optimized punctured ZCZPS) and analyze their properties especially their optimized cross correlation property of any two sequence-pairs in the set. Furthermore, we apply our newly provided triphase coded waveforms and equal gain combination technique to the system simulation, and study the performances versus different number of radars in RSN, with Doppler shift or not. Simulation results show that detection performances of multiradars (utilizing our optimized punctured ZCZPS and equal gain combination), either under the Doppler shift condition or not, are superior to those of singler radar.
