由Tufts与Kumaresan提出的修改的前后向线性预测(MFBLP)方法,在单次快拍的情况下,可用于传感器阵的测向。在一定的条件下,这种方法的“解相干性”被严格地证明。在另外一些条件下,详细讨论了由单次快拍(或相干信号源)所引起的周期性衰减。这个问题中的一种特殊情况叫Kumaresan-Prony情况(简记KP)。本文最后给出了模拟结果。
The modified forward-backward linear prediction (MFBLP) method proposed by Tufts and Kumaresan can be used for direction finding of the sensor array in the case of a single snapshot. Under certain conditions, the “coherence” of this method is strictly demonstrated. Under other conditions, the periodic attenuation caused by a single snapshot (or coherent signal source) is discussed in detail. A special case of this problem is the Kumaresan-Prony case (abbreviated KP). At the end of this paper, the simulation results are given.
