High-power and high-voltage pulse rigid modulator

Abstract

The invention discloses a high-power and high-voltage pulse rigid modulator which comprises the components of a trigger that outputs a double-polarity triggering pulse; a multipath modulating submachine which receives the double-polarity triggering pulse and generates multiple modulating pulses according to the double-polarity triggering pulse; a pulse transformer which receives the multiple modulating pulses and performs synthesis on the multiple modulating pulses for obtaining a target pulse; an energy storage unit which supplies electric power to the multipath modulating submachine; and a power supply unit which charges the energy storage unit. The high-power high-voltage pulse rigid modulator realizes flexible change of transmitting pulse width and repetition frequency and expands modulator power magnitude, thereby satisfying the requirement of modern radar to a transmitter.

Description

Technical field [0001] The invention relates to the technical field of high-voltage pulse modulators, in particular to a high-power high-voltage pulse modulator. Background technique [0002] High-voltage pulse modulators are divided into linear modulators and rigid modulators. At present, high-power linear modulators use hydrogen thyristors and thyristors as modulation switches; low-power rigid modulators use pulse modulation tubes and IGBTs as modulation switches. [0003] The disadvantage of linear modulators is that the modulation pulse width is determined by the pulse forming network (also called artificial line, simulation line), so that under the limitation of the maximum working ratio of the electric vacuum tube, the pulse width and repetition frequency are restricted, and it is difficult to meet the requirements of modern radar on the transmitter.

Problems solved by technology

[0003] The disadvantage of the linear modulator is that the modulated pulse width is determined by the pulse forming network (also called artificial line, artificial line), so that under the limit of the maximum working ratio of the electric vacuum tube, the change of the pulse width and repetition frequency is restricted, and it is difficult to meet the requirements of modern radars for transmitters. requirements

At present, although the rigid modulator can flexibly change the pulse width and repetition frequency under the limitation of the maximum working ratio of the electric vacuum tube, the power level of the modulator cannot be increased, and it cannot meet the requirements of modern radars for transmitters.
