Monopulse antenna

Schematic diagram of a monopulse antenna: All the antenna's radiators are divided into two groups, the feed lines of which are combined one in phase and one out of phase. This monopulse antenna has two feed lines: the sum and the difference channel.

The term monopulse antenna designs are of antennas combined that have two or four leads. With the signals of the different supply lines, different sums and differences can be formed for different purposes.

Monopulse antennas were originally developed for the monopulse method in pulse radar devices , which improves the accuracy of the measurement of angular coordinates in primary radar devices.

In secondary radars, monopulse antennas are used for sidelobe suppression .
