Then the regularization method to compute the geopotential coefficients is discussed and the spectral decomposition formula of the trace of the mean square error in the regularization solution constraint to Kaula s rule is derived.

The reason for deteriorated performance of conventional orthogonalization algorithms for adaptive jamming cancellation at low jamming to noise ratio (JNR) was analyzed.

Nulls shift from the interferences directions when the orthogonalization algorithm for adaptive beam- forming is used and the algorithm fails to work when the interferences are coherent.

It is well known that the orthogonalization algorithm is based on the signal subspace to resolve targets and it fails to work when interfering signals are coherent.
