DIGITAL COMPENSATOR OF BACKGROUND NOISE Russian patent published in 1997 - IPC

FIELD: radars. SUBSTANCE: device has weight matrix calculation unit and matrix-vector multiplication unit, which provide calculation of regular value of triangle factor L of matrix which is inverse to correlation one, and multiplication of input signal by this matrix and by its Hermitian conjugate. Calculation of regular value of matrix L provides high convergence speed. Usage of unitary rotation operations provides stability against limited bit-length of calculations. Corresponding device has (N-1) delay gates, weight matrix calculation unit, matrix-vector multiplication unit, N multipliers and group adder. EFFECT: increased speed. 5 cl, 4 dwg
