According to if there exists a one to one mapping between the two point sets to be matched, PPM can be divided into the case of complete matching and the case of incomplete matching. According to transformation type between the two point sets, PPM can be divided into the affine (including Euclidean and similarity) case and the projective case.

Unlike the uniform linear array,the unform circular array is able to provide 360°azimuthal coverage,within the mode space,it has the covariance matrix of the Toeplitz-like struture while all sources are uncorrelated,with which the noise variance can be made out directly,note that will eliminate an eigendecomposition when the ESPRIT is applied,consequently reduce the computational load.
对于均匀圆形阵列,在信源都是非相干信源的情形下,由于模式变换后的协方差矩阵具有类Toeplitz的特征,因此,我们可以根据这种特殊的性质,直接求得噪声分量,因此若使用ESPRIT算法进行波达方向估计,就可以避免第一次特征分解,较大程度上减少了计算量。
