Monopulse aerial network - uses two interlaced networks giving good sum and difference diagrams and having wide pass band

摘要

The monopulse aerial network has two non resonant interlacked plane networks. Each of these networks is made up of the same numb er of parallel radiating lines of identical length D. All the lines are regularly spaced at a distance at which is less than the half wavelength. Each line of the first network has N1 regularly spaced radiating sources. The spacing distance being d 1. They have an identical and symmetric amplitude distribution. Each line of the second network has N2 regularly spaced radiating sources N2 is not = N1. The spacing distance is d2. They have an amplitude distribution of the same form as the first network. The lines of each network are fed at their ends from a series distributor connected to an hybrid junction. This junction (H) delivers sum SIGMA and difference DELTA signals on two separate channels. The global amplitude distribution along the series distributors is symmetric with respect to the median axis of the network parallel to the lines.
