Title:
MODULATOR FOR PULSE RADAR TRANSMITTER
Document Type and Number:
Japanese Patent JPS55149067
Kind Code:
A
Abstract:

PURPOSE: To achieve miniaturization by making common the saturable coil and saturable transformer in the pulse radar transmitter having two or more kinds of pulse widths through the use of an air core coil for energy shift adjustment.

CONSTITUTION: An air core coil 16 for energy shift adjustment is connected between the 2nd SCR5 on the narrow side of pulse width and a saturable coil 6 and the relay contacts 17 for pulse width changing-over are connected to the increase PEN18 side for the purpose of widening the pulse width. In the radar transmitter having two kinds of pulse widths through selection of the inductance of said air core coil 16, the inductance of the saturable coil 6 and the λ (constant determined by a saturable transformer 7) of the saturable transformer 7 may be made constant simply by increasing the relay contacts 18 for pulse width changing-over and since the coil and transformer may be used commonly for two kinds of pulse widths, the saturable coil 6 and saturable transformer 7 may be made respectively one.
