Angular Accuracy of a Phased Array Radar

L. E. Brennan

ResearchPublished 1959

An approach to the theory of angle measurement with phased-array radars that use a set of separate antenna elements, each followed by an individual amplifier, in place of a more conventional receiving antenna. This study defines, for a phased array, the theoretical limit on angular accuracy that is set by receiver noise. It is shown that the accuracy of amplitude-comparison monopulse approaches this theoretical limit for large signal- to-noise ratios. The same accuracy can be achieved with phase-comparison monopulse by proper weighting of the individual signals.
