The radar system includes a sum and difference network coupled to a conventional monopulse type antenna. The difference signals or error signals are applied into a modulator in space quadrature with electrical vectors in a direction transverse to the direction of propagation polarized at right angles to each other. A rotating magnetic field in the modulator causes any energy that is in line with this field to be continually rotated and applied to a coupler that is sensitive. During search the shutter is closed so that only unmodulated sum energy is passe...
A radar lobing system comprising: sources of elevation error signals, azimuth error signals and sum signals, modulating means coupled to said sources of elevation and azimuth error signals for amplitude modulating the error signals at a selected lobing frequency, isolating means coupled to said modulating means for passing the modulated error signals therethrough, a microwave post coupled to said isolating means, circulating means having a first terminal coupled to said source of sum signals, a second terminal coupled to said microwave post and having a ...
