This paper presents a procedure for CIR beamforming that avoids SVD-like proceduresm and is derived from the classic CINR solution. The resulting nulls along the direction of the impinging interferers are of the same degree as those used in noise subspace procedures. The method is based on both the use of a temporal reference, available in the satellite payload, and on the spatial steered beamvector (the Applebaum solution). The resulting procedure is a valuable alternative to the classic covariance loading methods, as further matrix inversion is not required, and the noise estimate is derived from the existing hardware. Some results corresponding to a data relay satellite (DRS) scenario are reported.
