초록

Two distinctly polarized monopulse signals are orthogonally superimposed using antennas spaced in pairs which are transversely aligned. Signals from the pairs are separately summed and differentiated. Signals from both pairs are summed in one system. A transmitter supplies pulses directly to one pair and through a 90°phase shifter to the other pair.

청구항

The method of detecting objects with radar signals which comprises providing dual polarized, two plane monopulse radar signals by superimposing two single plane monopulse patterns, wherein both single plane monopulse patterns are singly polarized and one of the patterns is orthogonally polarized with respect to the other pattern, and requiring only two sum/difference power dividers for full implementation of the monopulse comparator.
