The method simultaneous excitation is considered of microwave oscillations in linear arrays of spark radiators. It is based on the voltage multiplication circuit’s usage. The influence is studied of the growing voltage along of antenna array and the switching time of dischargers in the array on performances of the directional diagram.

The method of control directional diagram array is based on short-duration pulse shape properties. The beam direction depends on pulse radiators excitation parameters. The parameters experimental probing results are given for linear antenna array of spark radiators.
