ABSTRACT:
A monopulse tracking system utilizing at least two channels, each of which has a different spreading/despreading pseudo-random noise function associated therewith. In conjunction with a monopulse antenna, one of the channels is utilized to develop a sum signal and the other channel is utilized to develop a difference signal, which sum and difference signals are utilized in a phase detector to generate an error signal. Because different channels are utilized to develop the sum and difference signals, externally generated noise is uncorrelated in the phase detector and, therefore, biases caused by the noise are eliminated.
