The study indicates that the TDOA estimation method based on spectral correlationl has better anti? jamming ability than the classical method of GCC, and this method can obtain the TDOA of each emitter unambiguously in the environment of multi? emitters.

• 研究表明,谱相关时差估计方法较之经典的广义互相关(cc)具有更强的抗干扰能力,在多辐射源环境下,该方法可以无模糊地估计各个辐射源的时差。
