Compared with the Primary Radar, the Secondary Surveillance Radar using the Monopulse Technology can measure the range and the azimuth of the targets more accurately.

A monopulse tracking technology of differential mode with emphasis on its working principle and realization method, and points for attention is introduced in this paper.

The technology of single channel monopulse tracking is widely used in air vehicle TT&C because of its simple equipment and high reliability.
