摘要: |
给出了一些噪声、干扰及低截获概率雷达信号的循环谱相关函数,分析了其在噪声与干扰中检测的优越性;对循环谱相关函数与Wigner-Ville分布、解线调、模糊函数进行了比较,分析了它们的一致性,并比较了循环谱相关函数的几种主要估计算法。从这些分析中可知,循环谱相关函数是检测低截获概率雷达信号的有效方法,抗干扰能力强,并具有实时处理的潜力和可能性。 |

Abstract: |
The SCFs of some noise, interfering and LPI radar signals are illustrated, the performance advantages of using SCF to detect LPI signals in noise or interference environments are analyzed. The SCF is also compared with Wigner-Ville distribution, dechirping and ambiguity, the equality among them is found. Moreover, several SCF algorithms are evaluated. It can be evidenced that the SCF is an efficient method of detection LPI signals, which has the good performance of resistance against the interference and the capability of realizing real time detection. |
Keywords: SCF LPI radar signals detection |
