在雷达传感器网络（RSN）中，合理设计波形可以有效降低不同雷达传感器之间的干扰。在本文中，我们进行了一些理论研究的相位编码波形在RSN共存。提出了一种新的三进制码-优化的删余零相关区序列偶集（ZCZPS），并分析了它们的性质。将新的三进制码和等增益合并技术应用于RSN，研究了不同条件下不同雷达传感器数目对RSN检测性能的影响。仿真结果表明，无论是否考虑多普勒频移，使用优化的删余ZCZPS的RSN都比使用相同数量的Gold码的RSN性能更好，并且比单雷达系统性能更好。
In the radar sensor network (RSN), the interferences among different radar sensors can be effectively reduced when waveforms are properly designed. In this paper, we perform some theoretical studies on coexistence of phase coded waveforms in the RSN. We propose a new ternary codes-optimized punctured zero correlation zone sequence-pair set (ZCZPS)-and analyze their properties. Applying the new ternary codes and equal-gain combination technique to the RSN, we study the detection performance versus different numbers of radar sensors under the different conditions. The simulation results show that the RSN using our optimized punctured ZCZPS performs better than the RSN using the same number of common codes such as the Gold codes and much better than the single radar system no matter whether or not the Doppler shift is considered.
